For each item that have access to a database table a list of filter objects can be created.
To create filters use an Filters Dialog of the Application builder.
Filters provide a convenient way for users to visually specify parameters of the request made by the application to the project database
Each filter has the following attributes:
owner– an item that owners this filter,
filter_name— the name of the filter that can be used in programming code
filter_caption- the name of the filter used in the visual representation in the client application,
filter_type— type of the filter, see Filtering records,
visible— if the value of this attribute is
true, a visual representation of this filter will be created by the create_filter_inputs method, when a
filtersoption is not specified,
value — a value of the filter,
All filters of the item are attributes of the
filters of its object.
filter_name we can get access to the filter object:
invoices.filters.invoicedate1.value = new Date()
Another way to get access to the filter is to use filter_by_name method:
invoices.filter_by_name('invoicedate').value = new Date()
