form-for

问题 I am a new Rails developer and I am having trouble using the bootstrap3 datetimepicker together with my rails form_for to save to a DateTime attribute in my ScheduledAccess Model. The one I am using is from http://eonasdan.github.io/bootstrap-datetimepicker/ Code: .form-group = f.label :start_time datetimepicker1.input-group.date = f.text_field :start_time, class:"form-control", id:"scheduled_access_start_time" span.input-group-addon span.glyphicon.glyphicon-calendar .form-group = f.label

问题 I have gone through tons of the form_for nested resource questions and can't get any of the solutions to work for me. I figured its time to ask a personalized question. I have two models, jobs and questions, jobs has_many questions and questions belong_to jobs. I used scaffolding to create the controllers and models then nested the resources in the routes.rb. root :to => "pages#home" resources :jobs do resources :questions end get "pages/home" get "pages/about" get "pages/contact" class Job <

问题 I want to change my User model's profile attribute which is just a string in a form_for. I am running into a problem where my password is getting set to blank when I update my profile attribute. That is, my user account has a password, but when I change my profile, my password becomes blank. The next time I try to log in, I just leave the password field blank.

问题 I get this page when incorrect form login details are entered: When credentials are correct the user is just logged in. When they're invalid this error page comes up. How do I catch this page and handle the error myself? E.G. redirect to same page or add the error to my array of errors rather than have this page show up? Controller: class UserController < ApplicationController def index end def new @user = User.new end def create @user = User.new(params[:user]) if @user.valid? user = Parse:

问题 I'm somewhat of a Rails newbie. I'm writing a couchrest-rails app, so am not using activerecord for this model. I just figured out that that means that form_for(@model) won't work. I'm trying to work out how to use form_tag -- but most of the examples don't involve new & create actions. This is wrong: <h1>New article</h1> <% form_tag new_article_url(@article), :method => :post do |f| %> <%= f.error_messages %> <p> <%= f.label :title %><br /> <%= f.text_field :title %> </p> <p> <%= f.submit
