[英]Rails ajax first request not showing up unless I refresh the page
I have a view that has a form to create a new post using Ajax, and it also renders all the posts and adds the newly added post to them. 我有一个视图,该视图具有使用Ajax创建新帖子的表单,它还呈现所有帖子并将新添加的帖子添加到其中。 The problem is when I post the very first post, the page does not show it unless I refresh, then if I refresh it shows up and when I add more posts Ajax works fine. 问题是,当我发布第一篇文章时,除非刷新,否则页面不会显示它,否则,如果我刷新它就会显示出来,并且当我添加更多文章时,Ajax可以正常工作。
Here is the view index.html.erb
: 这是视图index.html.erb
:
<%= link_to('Logout', destroy_user_session_path, :method => :delete) %>
<%= link_to 'Edit my account', edit_user_registration_path %>
<%= form_tag search_posts_path, method: :get do %>
<%= text_field_tag :search, params[:search] %>
<%= submit_tag "Search", name: nil %>
<% end %>
<b> Study requests </b>
<%= form_for(@post, remote: true) do |f| %>
<%=f.label :Course_name %>
<%=f.select :course_name, options_for_select(course_names) %><br/>
<%=f.label :Course_number %>
<%=f.select :course_number, options_for_select(course_numbers) %> <br/>
<%=f.submit %>
<% end %>
<%= render @posts %>
The partial is _post.html.erb
: 部分是_post.html.erb
:
div id="post">
<%= post.user_name%>
</div>
Controller : 控制器:
def index
@posts = Post.all.order('id DESC')
@post = Post.new
end
def create
@post = current_user.posts.build(post_params)
@post.save
respond_to do |format|
format.html { redirect_to @post, notice: "Study request successfully added" }
format.js {}
format.json { render json: @post, status: :created, location: @post }
end
end
And finally my create.js.erb
: 最后是我的create.js.erb
:
$("<%= escape_javascript(render @post) %>").prependTo("#post");
I got it, I only needed to add a new div around my partial rendering like this : 我知道了,我只需要在局部渲染周围添加一个新的div,就像这样:
<ul id="container">
<%= render @posts %>
</ul>
And change the create.js to append to this div 并更改create.js以追加到此div
