I have a model that may not have its entries deleted. I wish to have
all attempts to delete records raise a notification / error, report this
to the user, and return to the original page.
In my model file I put this:
def destroy
errors.add_to_base("Deletion prohibited!")
end
In the controller I have this:
# DELETE /entities/1
# DELETE /entities/1.xml
def destroy
@entity = Entity.find(params[:id])
respond_to do |format|
if @entity.destroy
flash[:notice] = 'Entity was destroyed.'
format.html { redirect_to(entities_url) }
format.xml { head :ok }
else
format.html { redirect_to(entities_url) }
format.xml { render :xml => @entity.errors,
:status => :unprocessable_entity }
end
end
end
This seems to work insofar as the records are not deleted. But the
error message is not displayed. What am I missing?
I know, just get rid of the delete link in the view. Eventually, yes,
right now I want to assure myself that no matter how the request comes
in the action is disallowed and an error is raised. I will probable
want to log the attempt as well.
