I am using Rails 3 under Windows Vista and have two tables: users and user_comments. user_comments.user_id should point to the user a comment is about. In my show view for user I have a link to the new method of user_comments to allow a comment to be created. This throws: Showing

I had a similar problem yesterday. I would go to the root of my site and I would get a Too Many Redirects message. It seems like there was an infinite loop. After struggling for over an hour yesterday late at night, it seemed like I fixed it. But now, when I want to create a New User, it''s redirecting me to the Sign In screen. Seems like I didn''t fix the problem completely. I

Hi everybody, I just started thinking about a project and am seeking some help regarding its design. The idea would be to create labels (i.e. address labels).I could let users type the text manually, but I dont think they would appreciate that when they''ll want to print 5000 addresses. I can also probably let them import csv files, that should not be a problem, but playing with those

Hi everyone, I am relatively new to rspec and I am running into a wall in testing my views. I have a RESTful resource Contracts with a nested resource of Line_items. I am trying to figure out how to test the "edit" form of the Line_items. What complicates this is the nested routing and how to account for it, and that there is a partial form (_form.haml) that both the edit.haml and

Greetings, I''m in the throws of deploying an app on site5, and I''m getting strange errors. I think I might need to understand how error_messages_for works. I get a pretty standard looking error: " You have a nil object when you didn''t expect it! You might have expected an instance of ActiveRecord::Base. The error occured while evaluating nil.errors Extracted

I''ve changed my destructive link_to statements in favor of button_to. But what if I want to make an .rjs call with that button? Seems like we need something equivalent to link_to_remote, so that the button can make an ajax request instead submitting the form. Or am I missing the point entirely?

I have an HTML form on the screen, that is connected to a database (standard Ruby way). I found that there are people that would rather not fill in this information, but would rather search Amazon for the info. Therefore, I added a link to the right of one of the fields that, when pressed, will search Amazon for what ever you typed into that field. So, how can I do that? At first I tried

It seems common to use RJS for quickly adding and highlighting a list that is having content added to it like this: http://rafb.net/paste/results/Z3m32g48.html ... where "my_list" would be an UL and the partial would insert a LI.
