Question

我想根据Hartl的教程实施用户评论。

我在Rails的控制台中执行此操作没有问题，但我遇到了表单问题。

表单可以保存但不保存内容：

INSERT INTO "reviews" ("reviewer_id", "reviewee_id", "created_at","updated_at") VALUES ($1, $2, $3, $4) RETURNING "id"  [["reviewer_id", 1], ["reviewee_id", 15], ["created_at", 2016-09-16 09:52:49 UTC], ["updated_at", 2016-09-16 09:52:49 UTC]]

这是用户模型：

has_many :active_reviews,   class_name: "Review",
                          foreign_key:"reviewer_id",
                          dependent: :destroy
has_many :passive_reviews,  class_name: "Review",
                          foreign_key:"reviewee_id",
                          dependent: :destroy
has_many :reviewing, through: :active_reviews, source: :reviewee
has_many :reviewers,  through: :passive_reviews, source: :reviewer

def review(other_user, great)
  active_reviews.create!(reviewee_id: other_user.id, content: great)
end

评论模型：

belongs_to :reviewer, class_name: "User"
belongs_to :reviewee, class_name: "User"
validates :reviewer_id, presence: true
validates :reviewee_id, presence: true

评论控制员：

class ReviewsController < ApplicationController
  before_action :logged_in_user, only: [:create, :destroy]


  def create
    @review = current_user.active_reviews.build
    @user = User.find(params[:reviewee_id])
    current_user.review(@user, :content)
    redirect_to reviews_user_path(@user)
    flash[:success] = "User reviewed"
  end

  def destroy
  end

end

观看次数（shared / _review_form.html.erb）：

<%= form_for(@review) do |f| %>
        <%= render 'shared/error_messages', object: f.object %>
        <div><%= hidden_field_tag :reviewee_id, @user.id %></div>
        <%= f.text_area :content, placeholder: "Leave a review..." %>
                    <%= f.submit "Submit", class: "btn btn-primary" %>
<% end %>

观看次数（users / user_reviews.html.erb）：

<% provide(:title, @title) %>
<div class="row">
  <aside class="col-md-4">
    <section class="user_info">
      <%= gravatar_for @user %>
      <h1><%= @user.name %></h1>
      <span><%= link_to "view my profile", @user %></span>
      <span><b>Microposts:</b> <%= @user.microposts.count %></span>
    </section>
    <section class="user_info">
      <%= render 'shared/review_form' %>
    </section>
    <% @reviews.each do |r| %>
    <ol class="users follow">
      <li><%= r.reviewer.name %>: <%= r.content %></li>
    </ol>
  <% end %>
 </aside>
</div>

Answer 1

我认为你没有打电话给'保存＆＃39;你的创建函数中的方法

例如：

def create

    #---your code----

    @reviews= Review.new(review_params)

    if @review.save
        redirect_to :action => 'list'
    else      
        render :action => 'new'
    end

end

Answer 2

谢谢我已经弄明白了

我的内容未插入，因为它是评论中的哈希

"review"=>{"content"=>"fsdfsdfsdf"}

解决方案

def create
  @user = User.find(params[:reviewee_id])
  @review = Review.create!(reviewer_id: current_user.id, reviewee_id:@user.id, content: params[:review][:content])
if @review.save
  redirect_to reviews_user_path(@user)
  flash[:success] = "User reviewed"
 end
end

def destroy
end
