I am trying to get data out of a database to my rhtml file.

There are a couple of things I find myself tweaking (or wanting to tweak, but never getting around to tweaking) each time I generate a new scaffold: 1) Change the layout from blah.html.erb to

Hello friends! I have an application to list different kinds of institution names. So I have one table "instits" for the institutions and another table "nome_instits" for their names.

Hi guys, I''m part way through a RoR application, for some reason whenever I add new controllers (using scaffold) I get an uninitialized constant [name of controller] error. The first few controllers work fine, the only thing I can see that I''ve changed is the layout file (but scaffold creates a new layout for each controller so can''t see that being the problem). You

So, the partial looks like this: <!-- _part.rhtml --> <tr> <td><%=part.number%></td> <td><%=part.associated_part_number%></td> <td><%=part.drawings%></td>

Hi, Is there any performance difference between rendering partials vs. calling a helper?

I tried to do this by making a radio button; if ''no date'' is selected, the date

Hi all I''m quite unsure what''s the point to have a create and update action in the Rails scaffolds... I guess the developers had good reason to implement them, but I don''t really see the reason for them... Why no just checking for get/post within the same new/edit method? def new unless request.post? # do the normal "new" stuff else # do the
