_form.rhtml isn't being updated automatically


#1

I have a problem with a new rails program i’ve just started.

I have a list page for my DB table, and all the CRUD stuff is working
fine, except that the ‘new’ and ‘edit’ pages don’t have all the form
components they should have: my db table has fields “id, title, url,
added_at”, and these are all listed on the list page. However, the
‘new’ has only a text field for title, and nothing for “url”.

When i’ve done this before (just with tutorials, i’m a rails noob), a
change to the DB was instantly reflected in the ‘new’ page, ie the
“_form.rhtml” page was automatically modified. This isn’t happening now
though. Does anyone know why?

thanks

By the way, i just checked and if i re-generate the scaffold then the
right boxes appear. I shouldn’t have to do this though should i? When
i worked through the tutorial (DHH’s weblog movie) then DB changes were
represented instantly in the form.

Scaffolding in the Controller (:scaffold) looks at the DB tables on
the fly and constructs the index, show and edit forms based on the
columns found. If you generate the scaffolding code (./script/
generate scaffold) it writes the current information into the files
within the project, so any updates to the DB will not be reflected.

At least that’s my recollection. You quickly out grow
scaffolding…
