Multiple record update and validation

Rails
1

I have a form which is used to update multiple records (of the same
model) at one time, which it successfully does, but when I try to add
vaildation to the form, it seems to be ignored.

Code from the update method of my controller:

def update
SurvCamera.transaction do
SurvCamera.update(params[:surv_camera].keys,
params[:surv_camera].values )
end
flash[:notice] = “Cameras successfully updated.”
redirect_to :action => ‘show’, :id => params[:id]

rescue ActiveRecord::RecordInvalid
render :action => ‘edit’
end

In the model, I have the following to validate that “location” field is
not empty:

validates_presence_of :location

Like I mentioned…the updates work fine, however when I try to edit
records and leave location empty, it still attempts to save the record
w/out first running validation. Any suggestions?

What do you mean by ‘attempts to save w/out first running
validations’? Do you mean you get an exception, or do you mean it
saves with invalid data, or do you mean it does not save the invalid
record but does not tell you that it has failed, or do you mean
something else?

Sorry…it saves with the invalid (empty) values. Thanks, Brian

Do your unit tests pass ok, in particular the one that checks that a
record cannot be saved with that field empty?

Which version of Rails are you using?
