I am making a simple BBS (Bulletin Board System) with ruby on rails3.
3 main modesl are Members/Categories/Articles.
Article 'belongs_to' Members Article 'belongs_to' Categories,
Article then have member_id/category_id columns in db table.
Member 'has_many' articles. Category 'has_many' articles.
When a specific user tries to write an article, I tried it by
def new @article = current_member.articles.new end and that automatically filled in a member_id section when an article is created without any form input or anything.
Now, what should I do if I want to automatically fill a category_id column of an article?? I believe every data related jobs should be done within model. However, I am passing in :category value through url
For example,
localhost:3000/articles/qna/new
would mean the article should have an category_id of 2 (assuming category with id=2 has name=qna, also, I did routing jobs that I can successfully get 'qna' from params[:category]).
Should I use
def create current_member.articles.build(:category => get_category_id_from_name(params[:category])) end ?
But is it okay? because I believe since models cannot access params variable, controller has to do the above job, and thats not 'rails way' I do not want to use nested form, because I do not want user to choose an category when they are writing. Its like, if there is a QnA board, and if user clicked 'write' button, that means user is writing in a QnA board.
