DESCRIPTION ^

 BingoX::Chromium provides the generic API for BingoX admin classes.
 BingoX::Chromium uses admin objects that wrap Carbon data objects

CLASS VARIABLES ^

Classes that inherit from BingoX::Chromium should have the following class variables:

METHODS ^

handler ( $r )

Apache handler gets a new display object object of the class it was called as and calls flow against it.

CONSTRUCTORS

new ( $r [, $conf [, $mode ] ] )

Given an apache request object, returns an Admin object of the class it was called as. It also sets the data_class, data_class_name, cgi, uri, displaymode (from $q), and section (from $q).

FLOW

flow ( )

Decides what display method (or save_data) to call based on the displaymode, and submit_type (found in the query object).

?? Is this the best order to check ??

postmodify_handler ( $method_name, [ $method_name_args ] )

This method decides what happens after you leave the "Modify" screen. It normally works by passing a method that gets called, but it's meant to be overloaded as a hook when flow() finishes saving data (or if you hit Cancel). That way you can save something and go somewhere else besides display_view(). It currently will always call $method against $self, so no static methods, please...

postadd_handler ( $method_name, [ $method_name_args ] )

Behaves exactly like postmodify_handler() (see above), but is called after the user exits the "Add a new <whatever>" screen.

DISPLAY METHODS

display_list ( )

Prints an HTML page meant for listing all objects in class.

display_list_buttons ( )

Displays the buttons for display_list(). Easy to overload if you want more buttons!

display_modify_buttons ( )

Displays the buttons for display_modify(). Easy to overload if you want more buttons! Just like display_list buttons.

display_view ( )

Prints an HTML page meant for viewing an object. Itterates through fieldlist calling display_row for each element.

display_view_buttons ( )

Displays the buttons for display_view(). Easy to overload if you want more buttons! Just like display_list buttons.

display_modify ( )

Prints an HTML page meant for modifying an object. Itterates through fieldlist calling display_row for each element.

display_admin_name ( )

Returns class defined Class description as a string.

hidden_fields ( )

A stub called by display_view() and display_modify() that you can overload in your subclass if you want the view or modify/add screens to have a custom title.

hidden_fields ( \%fields )

A stub called by display_view() and display_modify() that you can overload in your subclass if you want the view or modify/add screens to have extra hidden fields.

Or you can pass it a hash ref of hidden fields, were key = field name and value = field value

display_start_html( \%params )

Accessor method to $self->cgi->start_html(); Put into params exactly what you'd put in CGI::start_html(). Overload this in your admin class if you want to set any special BG,text,link colors, or anything else you want to pass to start_html()

display_search ( )

Prints an HTML page meant for limiting what appears on the display_list page.

Not Implimented Yet.

display_row ( $field )

Takes a column (field) name and prints a 2 columned table row where the left column has the fields descriptive name ($self->fieldname($field)) and the right column has the output of that fields method ($self->$field)

DATA METHODS

save_data ( [ \%data ] )
 Goes through the process of calling sanity, then get_data (to get the data out 
of the query object) and then db_obj->modify.
 Optionally takes data hashref as returned by get_data(), otherwise calls get_data() itself.  (This makes extension of save_data() possible without having to call get_data() twice.)
get_data ( [ $data, ] [ $fields ] )

Takes the fields hash (returned by $self->fields()) and the CGI object and returns a data hashref which can be sent to Carbon's new or modify You can optionaly pass a $data hash and a $fields hash which it will use.

OPTIMIZE

sanity ( )

Populates the _errors data instance in the case that the data does not conform to what is allowed to be entered into the database.

cpkey ( [ $db_obj ] )

Returns a string representing a single composite primary key joined by $self->qfd.

cpkey_params ($cpkey)

Returns a params hash from the cpkey string passed.

pcpkey ( )

Returns a cpkey with a class name + $qfd in front of it.

dbh ( )

Returns the object's database handle.

OPTIMIZE Needs work. Doesn't appear to use Carboniums dbh method thus thus doesn't use cached dbh.

get_list_hash ( [ $selection ] )

*** NEEDS TO BE REMOVED ***

Returns a hash ref of all the objects in the class it was called against. The hash is built from the pcpkey, and the data class' title_field, substr()'d to the data class' title_size or by default 80 chars.

OPTIMIZE

db_obj ( )

Retrieves and caches encapsolated DATA object based on whats in the query obect. Looks for pcpkey query param first and then for each primary key individually.

OPTIMIZE

CLASS VARIABLE METHODS

data_class ( ) =item db_class ( )

Returns the data class for the current display class (from the class variable $data_class).

data_class_name ( ) =item db_class_name ( )

Returns the rightmost part of the db_class name (thats the text right of the ::)

ui ( )

This method is a fallback method for the user interface for BingoX::Chromium. ui() contains the default colors for the forms created by BingoX::Chromium. To create a custom color scheme for a specific class or entire admin area create a ui() method in either the Admin class or the subclass and modify the details to your preference.

children ( )

Returns class defined children as an arrayref.

parents ( )

Returns class defined parents as an arrayref.

parent_class ( )

Returns cached parent class

adminuri ( )

Returns class defined URI as a string.

classdesc ( )

Returns class defined Class description as a string.

adminclass ( )

NEEDS POD

fieldlist ( )

Returns the class defined fieldlist as an arrayref.

fields ( )

Returns class defined fields hashref.

fieldname ( $field )

Takes a column name and returns a string with that field's pretty name as defined in the class defined field hash. This is the [0] element of that keys array value.

fieldtype ( $field )

Takes a column name and returns a string with that field's HTML type as defined in the class defined field hash. This is the [1] element of that keys array value.

fieldhtmloptions ( $field )

Takes a column name and returns a hashref with that field's HTML options as defined in the class defined field hash. This is the [2] element of that keys array value.

fieldrelclass ( $field )

Takes a column name and returns a string with that field's related class (if it exists) as defined in the class defined field hash. This is the [3] element of that keys array value.

fieldrelclasstype ( $field )

Takes a column name and returns a string with that field's related class (if it exists) as defined in the class defined field hash. This is the [3] element of that keys array value.

fieldoptions ( $field )

Takes a column name and returns a hashref with that field's options information as defined in the class defined field hash. This is the [4] element of that keys array value.

fieldsanity ( $field )

Takes a column name and returns a listref with that field's sanity information as defined in the class defined field hash. This is the [5] element of that keys array value.

SANITY METHODS

These methods can be overridden at any level to provide customized sanity checking. These methods always return an error message on failure, and an empty string on success.

sane_regex ( $data, $regex [, $error ] )

If $data matches the regular expression in $regex, returns an empty string. Otherwise, returns $error or a default error message.

sane_maxlength ( $data, $length )

Makes sure that $data is no more than $length characters long. Returns an error message on failure, an empty string on success.

sane_minlength ( $data, $length )

Makes sure that $data is at least $length characters long. Returns an error message on failure, an empty string on success.

AUTOLOAD (?????)

AUTOLOAD method - Figures out what method was being called by stripping the fully qualified portion of $AUTOLOAD out as $name. This method is expected to be a column name (an element of fieldlist). It then figures out what that columns fieldtype is from fieldtype($name). It then calls that type of HTML display method and passed $name to it.

REVISION HISTORY ^

 $Log: Chromium.pm,v $
 Revision 2.36  2001/11/14 23:12:26  gefilte
 save_data() - now optionally takes \%data, the result of get_data().

 RATIONALE :
        Consider a case when you want to override save_data() in a method which
 calls SUPER::save_data() (arguably a very useful feature.)  Now suppose that
 your save_data() method needs to see the result of get_data(), or possibly even
 manipulate those results (although that should be accomplished by overriding
 get_data()), before calling SUPER::save_data(). Before this change, the
 (arguably expensive) call to get_data() would need to be repeated.  With this
 change, passing a \%data to save_data() will circumvent the need for the
 second call.
        I considered using instance data to cache the results of get_data(), but
 since get_data() can be optionally called with a preset \%data hash this
 feature, while solving the efficiency problem, would open the door to more bugs.

        "Did you make sure the NO_BUGS flag is on?  Well that's your problem!"
                - Colin Bielen (paraphrase)

 Revision 2.35  2001/11/14 22:53:49  gefilte
 Fixed some POD

 Revision 2.34  2001/10/19 22:23:54  gefilte
 HTML_scrolling() - now sets -DEFAULT properly to what is in the database
        (don't know if this ever worked right, but it didn't when I tried it. check out the tiny diff :-)

 Revision 2.33  2001/10/12 00:50:34  gefilte
 display_modify() - fixed output of 'li' tags (cosmetic)

 Added support for fields of type 'password' :
        - added method HTML_password()
        - added special case to display_row() which displays the password field twice (for verification purposes) unless displaymode is 'view'
        - get_data() verifies that the two fields are alike, otherwise it sets and _error and blanks the field out (so it doesn't persist)
        - sanity() doesn't set the 'required' error if an error is already set

 N.B. - get_data() is setting an error state, normally only done by sanity(). This may not be the right approach, but I couldn't think of a more efficient one than this, since the field being verified (essentially the second password field) will not be examined by sanity().

 Revision 2.32  2001/10/05 01:31:31  gefilte
 HTML_checkbox() - made slightly MORE useful than the last revision!

 Revision 2.31  2001/10/04 23:28:00  gefilte
 get_data()
        - fixed procedures for parsing dates and checkboxes so that they
          do NOT add to the %$data hashref unless the data has in fact changed
          from what is in the $db_obj.

 HTML_checkbox() - made more usable :-)

        "If only there were evil people somewhere insidiously committing evil deeds and it were necessary only to separate them from the rest of us and destroy them.  But the line dividing good and evil cuts through the heart of every human being.  And who is willing to destroy a piece of his own heart?"
                - Aleksandr Isaevich Solzhenitsyn, novelist, Nobel laureate (1918-)

 Revision 2.30  2001/09/29 00:29:22  gefilte
 db_class(), db_class_name() - renamed to data_class(), data_class_name()
        - this is consistent with Cobalt's naming scheme
        - left symbolrefs to old names for backward compatibility
        - changed ALL calls and documentary references to these methods to new names
        - changed procedure to ascertain data_class to FIRST look at new class data member (below), then try using the standard BingoX class naming scheme

 added class data $data_class so that you can set an arbitrary class as your Carbon-based data class

 new() - uses data_class() methods to populate class data instead of figuring it out on its own

 fieldname(), fieldtype(), fieldhtmloptions(), fieldsrelclass(), rieldrelclasstype(), fieldoptions(), fieldsanity()
        - now verify the existence of array elements before attempting to read them (who thought you could get away with not doing this????)

 HTML_time(), HTML_day(), HTML_month(), HTML_year(), HTML_date()
        - now return undef if displaymode() is 'view' and referenced datetime field is empty

 fixed some documentation typos

 Revision 2.29  2001/09/27 18:10:22  gefilte
 save_data() - cleaned up $data prep
        ($data was verified twice! sanity() was being called twice! INSANITY!)

 Revision 2.28  2000/12/12 18:51:57  useevil
  - updated version for new release:  1.92

 Revision 2.27  2000/10/20 00:24:15  zhobson

 - corrected POD for main_index()
 - changed main_index()

 Revision 2.25  2000/09/20 21:03:27  dweimer
 Merged one last portion from the old tree.

 Revision 2.24  2000/09/20 21:00:22  dweimer
 Merged David's changes.
 His comment:
 handler() method now sets up Apache response settings instead of display_*() methods.

 Revision 2.23  2000/09/20 00:31:59  zhobson
 Fixed a scope warning in flow() (used "my $other_class" twice in the same scope)

 Revision 2.22  2000/09/19 23:40:59  dweimer
 Version update 1.91

 Revision 2.21  2000/09/13 20:58:27  adam
  - in get_data, changed how dates are handled if SHOW_24HOURS is off

 Revision 2.20  2000/09/12 16:03:35  david
 Made Data::Dumper optional -- only called when $debug is activated.  Changed all of its calls to Data::Dumper::Dumper().
 Caused handler to return result of flow(), flow ends up returning results of display_*(), display_*() methods now return Apache response constants.

 Revision 2.19  2000/09/08 22:06:24  colin
  - get_data - if the field is a date it makes sure there is at least
    the year in the query object.  Before it would break if you had a year
    in your %fields hash, but were not submitting that datefield in your
    add or modify form.  get_data would blindly try and build a date.

 Revision 2.18  2000/09/08 21:31:23  thai
  - cleaned up the code

 Revision 2.17  2000/09/08 05:19:38  thai
  - turned off debug

 Revision 2.16  2000/09/08 03:19:09  adam
  GENERAL
    Added parent/child relationship functionality, where each class can
    specify parent and child classes.  These are used to display buttons
    at the bottom of the display list screens to access your parents or
    children based on the selected item in the list.

  - updated POD
  - new
      - now accepts a CGI as an optional 4th param.
      - sets the selection from the $q->param('parent_pcpkey');
      - sets the parent_class object var from the $q->param('parent_pcpkey')
  - flow
      - checks to see if you are entering from a parent or child and sets
        $q->param('parent_pcpkey') with whats passed.
      - Gets the desired child or parent admin object and calls flow against it.
      - added debugging
  - changed all occurances of $q->startform to try and print $self->adminuri
    as the ACTION.  If there is no adminuri it uses uri as before.
  - display_list
      - displays information at the top of the page about what parent you
        came from (if there is a parent)
  - all forms now include hidden for parent_pcpkey
  - display_list_buttoms
  - displays buttons to view the display list page of any child or
           parent classes you might have.
  - pcpkey
    - renamed qkey to pcpkey
    - changed all occurances of qkey to pcpkey
  - cpkey
    - cpkey now just calls cpkey against the db_obj
  - cpkey_params
    - calls cpkey_params against your data_class
  - added children and parents class var accessor methods
  - HTML_popup
    - if your displaymode is add and you have a parent_pcpkey it attempts to
      select the parent in the pop-up menu.

    and HTML_time()

 corrected some minor ui bugs in display_list() and display_modify()

 Revision 1.26  2000/02/18 23:38:56  colin
 - altered sanity() so that it now accepts a passed \%data hashref instead
   of looking for things in the query object. this way the data is already
   formatted and we don't have to format data again (especially useful because
   we don't have to re-sort all the date fields, etc)

 Revision 1.25  2000/02/17 23:37:43  colin
 -get_data() now gives meaningful error messages when users enter invalid info in date fields

 Revision 1.24  2000/02/17 03:46:27  dougw
 Small modifications to take advantage of DateTime changes.
 Using $obj instead of $obj->time_local;

 Revision 1.23  2000/02/11 18:52:00  colin
 - (doug) HTML_* methods now use DateTime to manage date info.
 - (colin) Changed ui() so that a) it caches the hasref if called as an object method and b)
   allows you to override default settings (and add others) when calling the method, as
   opposed to calling SUPER::ui() and then re-setting the resulting hashref.

 Documentation fixes and updates

 Revision 1.18  2000/01/31 02:00:19  adam
  - dbh was using a GLOBAL flag to see if had already set the
   $r->register_cleanup.  That was bad since the global was living beyond
   each hit.  In the end, the DBH wasn't being cleared after every hit.
   So now it uses the Apache notes to store the flag.
 - display_row() - oops...  thats not the variable name!

 "The best laid plans..."

 Revision 1.17  2000/01/30 04:30:46  adam
  - using an HTMl fieldtype of 'row' makes display_row() not print table
   tags, it just prints the results of the method $_().

 Revision 1.16  2000/01/27 22:12:17  colin
 Added cgi() and marked CGI_obj() as deprecated (evil music here).
 Added some \%qoptions to HTML_file

 Revision 1.15  2000/01/27 01:17:14  colin
 - finished HTML_file(). Also, due to popular request, display_modify() now uses
   $q->start_multipart_form() instead of $q->startform().
 - Well, it actually wasn't a *popular* request, but when the email went out asking
   if anyone had problems with it there was no response. 
 Ever. And that's good enough for me!

 Revision 1.14  2000/01/25 20:55:48  colin
 added:
 postmodify_handler()
 postadd_handler()
