#action_column(opts = {}, &block) ⇒ Object
Adds a column with checkboxes for each record. Useful for actions with multiple records, for example, deleting selected records. Please note that action_column
only creates the checkboxes and the ‘Select All’ and ‘Deselect All’ buttons, and the form itelf as well as processing the parameters should be taken care of by the application code.
-
:param_name
- The name of the HTTP parameter. The complete HTTP parameter is"#{grid_name}[#{param_name}][]"
. The default param_name is ‘selected’. -
:html
- a hash of HTML attributes to be included into thetd
tag. -
:select_all_buttons
- show/hide buttons ‘Select All’ and ‘Deselect All’ in the column header. The default istrue
. -
:object_property
- a method used to obtain the value for the HTTP parameter. The default isid
.
You can hide a certain action checkbox if you add the usual block to g.action_column
, just like with the g.column
definition. If the block returns nil
or false
no checkbox will be rendered.

#column(opts = {}, &block) ⇒ Object
Defines everything related to a column in a grid - column name, filtering, rendering cells, etc.
column
is only used inside the block of the grid
method. See documentation for the grid
method for more details.
The only parameter is a hash of options. None of them is optional. If no options are supplied, the result will be a column with no name, no filtering and no sorting.
-
:name
- Name of the column. -
:html
- a hash of HTML attributes to be included into thetd
tag. -
:class
- a shortcut for:html => {:class => 'css_class'}
-
:attribute
- name of a database column (which normally correspond to a model attribute with the same name). By default the field is assumed to belong to the default table (see documentation for theinitialize_grid
method). Parameter:model
allows to specify another table. Presence of this parameter-
adds sorting capabilities by this field
-
automatically creates a filter based on the type of the field unless parameter
:filter
is set to false. The following filters exist for the following types:-
string
- a text field -
integer
andfloat
- two text fields to specify the range. Both limits or only one can be specified -
boolean
- a dropdown list with ‘yes’, ‘no’, or ‘-’. These labels can be changed inlib/wice_grid_config.rb
. -
date
- two sets of standard date dropdown lists so specify the time range. -
datetime
- two sets of standard datetime dropdown lists so specify the time range. This filter is far from being user-friendly due to the number of dropdown lists.
-
-
-
:filter
- Disables filters when set to false. This is needed if sorting is required while filters are not. -
:filter_type
- Using a column filter different from the default filter chosen automatically based on the data type or the:custom_filter
argument. Seelib/columns/column_processor_index.rb
for the list of available filters. -
:ordering
- Enable/disable ordering links in the column titles. The default istrue
(i.e. if:attribute
is defined, ordering is enabled) -
:model
- Name of the model class to which:attribute
belongs to if this is not the main table. -
:table_alias
- In case there are two joined assocations both referring to the same table, ActiveRecord constructs a query where the second join provides an alias for the joined table. Setting:table_alias
to this alias will enable WiceGrid to order and filter by columns belonging to different associatiations but originating from the same table without confusion. See README for an example. -
:custom_filter
- Allows to construct a custom dropdown filter. Depending on the value of:custom_filter
different modes are available:-
array of strings and/or numbers - this is a direct definition of possible values of the dropdown. Every item will be used both as the value of the select option and as its label.
-
Array of two-element arrays - Every first item of the two-element array is used for the label of the select option while the second element is the value of the select option
-
Hash - The keys of the hash become the labels of the generated dropdown list, while the values will be values of options of the dropdown list:
-
:auto
- a powerful option which populates the dropdown list with all unique values of the field specified by:attribute
and:model
.:attribute
throughout all pages. In other words, this runs an SQL query withoutoffset
andlimit
clauses and withdistinct(table.field)
instead ofdistinct(*)
-
any other symbol name (method name) - The dropdown list is populated by all unique value returned by the method with this name sent to all ActiveRecord objects throughout all pages. The main difference from
:auto
is that this method does not have to be a field in the result set, it is just some value computed in the method after the database call and ActiveRecord instantiation.But here lies the major drawback - this mode requires additional query without
offset
andlimit
clauses to instantiate all ActiveRecord objects, and performance-wise it brings all the advantages of pagination to nothing. Thus, memory- and performance-wise this can be really bad for some queries and tables and should be used with care.If the method returns a atomic value like a string or an integer, it is used for both the value and the label of the select option element. However, if the retuned value is a two element array, the first element is used for the option label and the second - for the value. Read more in README, section ‘Custom dropdown filters’
-
An array of symbols (method names) - similar to the mode with a single symbol name. The first method name is sent to the ActiveRecord object if it responds to this method, the second method name is sent to the returned value unless it is
nil
, and so on. In other words, a single symbol mode is a case of an array of symbols where the array contains just one element. Thus the warning about the single method name mode applies here as well.If the last method returns a atomic value like a string or an integer, it is used for both the value and the label of the select option element. However, if the retuned value is a two element array, the first element is used for the option label and the second - for the value. Read more in README, section ‘Custom dropdown filters’
-
-
:boolean_filter_true_label
- overrides the label fortrue
in the boolean filter (wice_grid.boolean_filter_true_label
inwice_grid.yml
). -
:boolean_filter_false_label
- overrides the label forfalse
in the boolean filter (wice_grid.boolean_filter_false_label
inwice_grid.yml
). -
:allow_multiple_selection
- enables or disables switching between single and multiple selection modes for custom dropdown boxes.true
by default (seeALLOW_MULTIPLE_SELECTION
in the configuration file). -
:filter_all_label
- overrides the default value forBOOLEAN_FILTER_FALSE_LABEL
(‘--
’) in the config. Has effect in a column with a boolean filter or a custom filter. -
:detach_with_id
- allows to detach the filter and render it after or before the grid with thegrid_filter
helper. The value is an arbitrary unique identifier of the filter. Read section ‘Detached Filters’ in README for details. Has effect in a column with a boolean filter or a custom filter. -
:in_csv
- When CSV export is enabled, all columns are included into the export. Setting:in_csv
to false will prohibit the column from inclusion into the export. -
:in_html
- When CSV export is enabled and it is needed to use a column for CSV export only and ignore it in HTML, set this parameter to false. -
:helper_style
- Changes the flavor of Date and DateTime filters. The values are:-
:standard
- the default Rails Date/DateTime helper -
:calendar
- a Javascript popup calendar control
-
-
:negation
- turn on/off the negation checkbox in string filters -
:auto_reload
- a boolean value specifying if a change in a filter triggers reloading of the grid. Works with all filter types including the JS calendar, the only exception is the standard Rails date/datetime filters. The default is false. (seeAUTO_RELOAD
in the configuration file).
The block parameter is an ActiveRecord instance. This block is called for every ActiveRecord shown, and the return value of the block is a string which becomes the contents of one table cell, or an array of two elements where the first element is the cell contents and the second is a hash of HTML attributes to be added for the <td>
tag of the current cell.
In case of an array output, please note that if you need to define HTML attributes for all <td>
‘s in a column, use html
. Also note that if the method returns a hash with a :class
or 'class'
element, it will not overwrite the class defined in html
, or classes added by the grid itself (active-filter
and sorted
), instead they will be all concatenated: <td class="sorted user_class_for_columns user_class_for_this_specific_cell">
It is up to the developer to make sure that what in rendered in column cells corresponds to sorting and filtering specified by parameters :attribute
and :model
.

#row_attributes(&block) ⇒ Object
Optional method inside the grid
block, to which every ActiveRecord instance is injected, just like column
. Unlike column
, it returns a hash which will be used as HTML attributes for the row with the given ActiveRecord instance.
Note that if the method returns a hash with a :class
or 'class'
element, it will not overwrite classes even
and odd
, instead they will be concatenated: <tr class="even highlighted_row_class_name">
