Unknown column ‘images.id’ in ‘order clause’: SELECT * FROM medias WHERE ( (medias.`type` = ‘Image’ ) ) ORDER BY images.id asc LIMIT 0, 25

as far as i found out, its around line 362 in lib/ajax_scaffold_plugin.rb, but I hesitate to change anything in the generated code there.

another thing: I use the globalize plugin, which stops working unless i remove all .rjs and .rhtml extensions from the action names in lib/ajax_scaffold_plugin.rb:

return render#{suffix}_template(:action => ‘edit.rjs’) if request.xhr?

so far, nothing broke. I believe globalize uses some funky overrides with the template search path, it tries to detect language-specific template files (index_en.rhtml).

Other than that, fine work, that plugin!

Thanks for the feedback. We haven’t tried it yet with the Globalize plugin, but I will get it installed and check your fix works.

I have to admit single-table inheritance isn’t something I have considered so far in developing the plugin. If I had, I would of realised it would not work with the current code. I will add this to the list of things to look at.

Thanks again
Scott.

How would you go about adding a custom column to the form only for ‘create’? I have a relationship between two models ‘Program’ and ‘Project’ – a Program has_many Projects, and a Project belongs_to a Program.

What I want is to have a drop-down when you are creating a Project with a list of Program names. The id of whatever Program you selected would then be populated in the program_id of the new Project. You would then of course see the Program name in the table. When editing, the field could be read-only (i.e. can’t change programs once created). So far I’m using a single ‘Admin’ controller.

thanks!

Both the create and edit actions render the _new_edit.rhtml template and pass in a hash of options including :action. So the easiest thing to do would be customize (copy it from views/ajax_scaffold to views/project to get customization specific to the model) _new_edit.rhtml to do a check on @options[:action] and render a new template (say views/project/_create.rhtml) for the create action. You would also need to copy over _form.rhtml and edit that to get a read only value for the program field (maybe even call it _edit.rhtml!!)

So something like:

<pre>
<% if @options[:action].match(‘create’) %>
<%= render :partial => scaffold_partial_path(‘create’), :locals => { :scaffold_class => @scaffold_class, :scaffold_name => @scaffold_singular_name } %>
<% else %>
<%= render :partial => scaffold_partial_path(‘edit’), :locals => { :scaffold_class => @scaffold_class, :scaffold_name => @scaffold_singular_name } %>
<% end %>
</pre>

There is an example of a custom form in the comments of this "post":http://blog.caronsoftware.com/articles/2006/09/02/getting-started-with-the-ajax-scaffold-plugin

Does that help?

Building on your explanation for JJ; it seems there’s no elegant way to do for pages with many tables?

The naming convention used elsewhere doesn’t seem to work – I had expected _new_edit_{prefix}.rhtml to do the trick, but putting that file in place makes the ajax calls die. Peeking in the code (lib/ajax_scaffold_plugin.rb line 253, 272) seems to confirm that this is not supported right now – or am I misreading the code?

Thanks,
Ward.

Do you mean many tables on the same page? If so it is outlined in this "post":http://blog.caronsoftware.com/articles/2006/09/02/getting-started-with-the-ajax-scaffold-plugin.

If you mean having nested tables representing a has_many relationship, not at the mo.

Scott.

def default_{pluralname of scaffold goes here}_sort
"{realtable_name}.id"
end

so if your saffold line looks like this

ajax_scaffold :verygood_user

your override would look something like this

def default_verygood_users_sort
"users.id"
end

When trying to have :eval => "link_to(‘ddd’, ‘http://xxx’) , I get only the html itself as TEXT in the table (i.e. <a href…>), while it should have been displayed as a clickable hyperlink.
Can someone please advise on what am doing wrong here?
(BTW, I’m using the plugin version)

@Ariel – thats because the data is being sanitized. You will need to set the sanitize option on that column to false.

@rafamvc – this is upcoming in version 4.0 of the plugin….
