Add in true/false for click sortable using sortable option, matching this to the way it is handled in node.views.inc. Also move 'allow_empty' option to field definition and add it to all elements to make it available to Views everywhere it might be used.

#240440 Must use $view->render() instead of $view->execute() to generate the view or pre_render() won't get triggered.

A couple more fixes needed to get the new filter operator working correctly. We don't need to mess with the form element here, and the form element must return an array instead of a value, so just remove that part.

The many_to_one operator looks like it makes more sense to use as the default filter for fields with allowed values lists.

Add allowed values to the in_operator_content handler to automatically populate the options list with the results of either hook_allowed_values() or content_allowed_values().

Re-organize the Vews field handlers into a basic one that just adds the fields and formatters and a more complex one that adds in the group multiple values handling. Field modules can extend either one, depending on their needs.

Also add in a basic sort handler that just adds field info to the regular sort handler.

#63240 Add field permissions with new content_permissions module and related fix to views handling to implement permissions in Views, patch by moshe weitzman. thx moshe!!

Add smarter handling for arguments and sorts based on column type and sortable settings, and get rid of outdated Views 1 code that is no longer being used.

Update nodereference use of Views as selectors to add node titles and node title filters to view and use that filter.

Change the field group to be the field name, instead of 'Field', so we will see 'Text: field_my_field' instead of 'Field: field_my_field' as labels for fields, filters, etc.

Re-name fields to use Views 1 naming like field_text_value instead of field_text to make updates easier, and alter content.views_convert.inc to match.

Add default filters for all fields, and update fields to switch from string or numeric filters to 'in' operators if there are lists of allowed values.

Add helper function to return Views table name to make it easier to change the tablename in the future, like if we find a way to avoid the need to alias each field as its own table.

'group multiple values' views handler messes the query in various ways,
and is not needed to begin with : the nids we retrieve are selected by the
main views query, which already goes through a db_rewrite_sql.

#186775 - nodereference : fix 'Invalid argument supplied for foreach()' + buggy display when using 'full node' formatter and the referenced node has been deleted

The $this->nid_field got renamed in Views when the relationships patch hit, need to rename it here, too.

Does not work for optionwidgets yet.

load field data in one query per field (instead of one per field and per node previoulsy).
More optimisations could possibly be made there (fetch from cache ?)
Suggested by Adrian and Earl.

better detection of node forms in fieldgroup_form_alter (was causing warnings on views with exposed filters)

#168526 followup : import/export display settings - fix typo I introduced when committing the patch.

A little more cleanup of the option to use views for nodereference select lists. Using views for autocomplete is not yet working.

Re-implement the option to use a view to populate the nodereference selector. Still needs more work, but is basically functional for a select list. Nothing done yet about handling arguments or filters or using this in an autocomplete.
