Jifty::View::Declare::CRUD(3) User Contributed Perl Documentation Jifty::View::Declare::CRUD(3)

Jifty::View::Declare::CRUD - Provides typical CRUD views to a model 

  package App::View::User;
  use Jifty::View::Declare -base;
  use base qw/ Jifty::View::Declare::CRUD /;

  template 'view' => sub {
      # customize the view
  };

  1;

  package App::View::Tag;
  use Jifty::View::Declare -base;
  use base qw/ Jifty::View::Declare::CRUD /;

  template 'view' => sub {
      # customize the view
  };

  1;

  package App::View;
  use Jifty::View::Declare -base;

  use Jifty::View::Declare::CRUD;

  # If you have customizations, this is a good way...
  Jifty::View::Declare::CRUD->mount_view('User');
  Jifty::View::Declare::CRUD->mount_view('Category', 'App::View::Tag', '/tag');

  # Another way to do the above, good for quick and dirty
  alias Jifty::View::Declare::CRUD under '/admin/blog', {
      object_type => 'BlogPost',
  };

This class provides a set of views that may be used by a model to display Create/Read/Update/Delete views using the Template::Declare templating language.

Basically, you can use this class to do most (and maybe all) of the work you need to manipulate and view your records.

Call this method in your application's view class to add the CRUD views you're looking for. Only the first argument is required.

Arguments:

MODELCLASS
This is the name of the model that you want to generate the CRUD views for. This is the only required parameter. Leave off the parts of the class name prior to and including the "Model" part. (I.e., "App::Model::User" should be passed as just "User").
VIEWCLASS
This is the name of the class that will be generated to hold the CRUD views of your model. If not given, it will be set to: "App::View::MODELCLASS". If given, it should be the full name of the view class.
/path
This is the path where you can reach the CRUD views for this model in your browser. If not given, this will be set to the model class name in lowercase letters. (I.e., "User" would be found at "/user" if not passed explicitly).

This method returns the type of object this CRUD view has been generated for. This is normally the model class parameter that was passed to "mount_view".

This is the full name of the model class these CRUD views are for. The default implementation returns: 

  Jifty->app_class('Model', $self->object_type);

You will want to override this (in addition to "object_type") if you want to provide CRUD views in a plugin, or from an external model class, or for one of the Jifty built-in models.

This is a helper that returns the path to a given fragment. The only argument is the name of the fragment. It returns a absolute base path to the fragment page.

This will attempt to lookup a method named "fragment_for_FRAGMENT", where FRAGMENT is the argument passed. If that method exists, it's result is used as the returned path.

Otherwise, the "fragment_base_path" is joined to the passed fragment name to create the return value.

If you really want to mess with this, you may need to read the source code of this class.

This is a helper for "fragment_for". It looks up the current template using "current_template" in Template::Declare::Tags, finds it's parent path and then returns that.

If you really want to mess with this, you may need to read the source code of this class.

Given an $id, returns a record object for the CRUD view's model class.

Returns a list of all the column names that this REST view should display. Defaults to all argument names for the provided "ACTION". If there is no action provided, returns the "record_class"'s "readable_attributes".

Returns a list of all the columns that this REST view should display for update. Defaults to the "display_columns", without "id".

Returns a list of all of the columns that this REST view should display for create. Defaults to "edit_columns".

Renders a particular field in a given mode (read, create, edit). This attempts to dispatch directly to a method with the given field name. For example, if the subclass has, say, an "edit_field_post" method, then it will be preferred over the generic "edit_field" method.

Displays the column as read-only.

Displays the column for a create form.

Displays the column for an edit form.

The title for the CRUD page

Contains the master form and page region containing the list of items. This is mainly a wrapper for the "list" fragment.
The search fragment displays a search screen connected to the search action of the module. If your subclass can "search_fields", then that method will be called and the return value (which should be a list) will be used as a list of fields to render. Otherwise, all the fields of the Search action are displayed.

See Jifty::Action::Record::Search.

This fragment displays the data held by a single model record.

Used by the view fragment to show the edit link for each record.

The update fragment displays a form for editing the data held within a single model record.

See Jifty::Action::Record::Update.

The controls we should be rendering in the 'edit' region for a given fragment

The list template provides an interactive list for showing a list of records in the record collection, adding new records, deleting records, and updating records.

This routine returns how many items should be shown on each page of a listing. The default is 25.

Sort by field toolbar
The private template makes use of the "predefined_search" constant, which contains a list of hashref, each defines a collection in the format: 

  { name => 'my_list',
    label => "My List",
    collection => defer {
      # ... construct and return the collection
    }
  },
  { name => 'my_list2',
    label => "My List2",
    condition => [
       { column => 'foo' value => 'bar' },
       # ... and your other Jifty::DBI::Collection limit args
    ]
  }

This private template renders a region to show an expandable region for a search widget.

This private template renders a region to show a the "new_item" template.

Prints "No items found."

Renders a div of class list with a region per item.

Paging for your list, rendered at the top of the list

Paging for your list, rendered at the bottom of the list

Renders the action $Action, handing it the array ref returned by "display_columns".

Renders the action $Action, handing it the array ref returned by "display_columns".

The new_item template provides a form for creating new model records. See Jifty::Action::Record::Create.
