问题 Maybe I'm missing something obvious (hopefully), but I'm encountering a weird problem saving records in a nested form. It's a pretty basic setup, with a minor complication in that my LineItem model is a two-word relationship (:line_items). However, I've followed Rails guidelines and it seems to be working OK. My fixtures are creating the proper relationships between line_items and invoices, and everything is showing up properly in my views, but I can't get any line_item records to save

问题 How can I fix this error? This issue is created when I check the rails version in a demo created website using this command. 回答1: you can also use another debugger gem 'pry', '0.9.12.6' and remove gem 'byebug' . Then run bundle install 回答2: The output in yellow is asking you to run bundle install instead of gem install You should do that. Update: It looks like the windows version build is failing. Only passes for ruby 2.0.0 but not for above versions. You can check the status at byebug's

问题 I wanna join 2 table, games and game_logs. I did it this: game_joins = Game.joins(:game_logs) It worked. But the thing is I only want to join where the player_id = 1(for example).

问题 I am attempting what I would think is simple, but I have had zero luck in finding a solution that is similar AND easily adaptable to my problem. I have a view with a select dropdown which only contains months (January-December). I want the user to be able to choose a month and click a link_to button and retrieve a subset of records where the billDate field contains the month in question, I don't care about the day, and the records will always be the current year. I have used the following...

问题 I have looked around but I haven't really found an answer that seals the deal 100% for my individual situation. In my Ruby app, I have a user share system where members can post 'stuff'. Well, sometimes members post links, and I have noticed as the site grows, more and more users are complaining about there not being clickable links. How would I utilize regular expressions to match urls for links in posts. Furthermore, how would I apply this in my Model? Thanks for you help, out of all my

问题 I am trying add a fake input to simple_form using the following suggestion (rails simple_form fields not related to the model), but it does not work for me.
