Disclaimer: RoR newbie. Using the acts_as_taggable plugin. As an exercise I wanted to switch from the destructive TAG_WITH method to adding tags while preserving the existing ones.

I''ve installed the acts_as_taggable plugin and modifed it according to the tutorial form making it user specific (http://www.slashdotdash.net/blog/articles/2006/04/29/acts_as_taggable-per-user-tagging ). I keep getting errors when I try to tag things, however, and have traced the problem to the line of the tag_with function that calls the find_or_create_by_name function. So I fired

I have a model named Project which contains a name attribute, and I have a second model named Booking which has, among other things, a date and a Project. (has_many :bookings, belongs_to :project). When a user creates a new Booking, they have the option of using an existing Project or creating a new Project. As an added complexity, when choosing from existing Projects, they can either choose from

Hello everyone, I have a rails app which uses email as login name. At some point, I have to search the user, in the User model by email. For some reason, the method User.find_by_email(email) returns nil, even though the user is in the database. The same applies for any find_by_* method that searches by any database column. I was able to find the user using the User.find Does anyone have an idea

OK - I know this has been asked before, but I cannot find it in the archives. Forgive me if I''m creating more noise than I should. I want to know the easiest way to deal with this scenario: I have articles. I have categories for the articles. On the form where you write an article, there needs to be a free-form field to entire the category. The create() method will build the

Ok, maybe I''m being particularly thick, but I''ve been trying to find the solution to this for a couple of hours now and I just can''t seem to be able to do it... I''m trying to write a step as such: Given("user $email is logged in") do |email| user = User.find_by_email(email) session[:user_id] = user.id end This is the way it would

Since there''s no ''exists?'' method for a has_many collection, is there an easier way to avoid adding duplicates to a collection? (I assume obj.items << item would add duplicates if repeatedly called.) Right now I do: category = Category.find_or_create_by_name(category_name) directory.categories << [ category ] if directory.categories.find(:first,

I have a Post model, which is linked to the Tag model via a has_and_belongs_to_many relationship and a join table. Post also has handy tagstring and tagstring= methods that allow you to define tags by space-delimited strings. The problem is this. Whether I assign a list of tags with the tagstring= method or use p.tags << to form the list of tags, if (on a newly-created post) I try to

Hi all, I''m trying to extend the tagging functionality of has_many_polymorphs to work with user owned tags - ie, putting belongs_to :user in the Tagging model. So I changed the index in the generated migration, and added user_id to the taggings table. Then I added belongs_to :user in the Tagging model. In the lib/tagging_extensions.rb file I added a new function: def

Hello, I''ve noticed that I can''t save my object to the DB after using ''unshift'' on one of Array fileds. Ex: (below ''tags'' is a collection in object ''transaction'') transaction.tags.unshift(Tag.find_or_create_by_name(name)) transaction.save! Everything is fine when I am using ''<<'' to append tag to

Hi, Have an issue with the rails auto complete, it works fine but I don''t know how to find the id element search in the textfield.
