重複の可能性:
Rails-新規/作成アクション用のAJAX
イベントのパーシャルを含むタイムラインがあるので、タイムラインで直接イベントをCRUDできます。削除部分は正常に機能しているので、イベントが削除されるたびに削除部分とタイムラインが更新されます。ただし、新しいイベントが作成されたときに機能させることができません。フォームとタイムラインを更新する代わりに、ページ全体が更新されます。
これはコントローラーと関係があると思いますか?しかし、私はそれを修正できないようです。どんな助けでも大歓迎です、ありがとう:0)
イベントコントローラー:
def create
@event = Event.new(params[:event])
respond_to do |format|
if @event.save
format.html { redirect_to @event.timeline, notice: 'Event was successfully created.' }
format.json { render json: @event, status: :created, location: @event }
format.js
else
format.html { render action: "new" }
format.json { render json: @event.errors, status: :unprocessable_entity }
format.js
end
end
end
タイムライン/ショー:
<div id="new-event">
<%= render :partial => "new_event", :locals => { :event => Event.new(:timeline_id=>@timeline.id) }, :remote => true %>
</div>
タイムライン/_new_event:
<br />
<h2>Add an event</h2>
<h4>Fill in the form and click 'Create Event' to add a new event to the timeline.</h4>
<%= form_for(event) do |f| %>
<% if event.errors.any? %>
<div id="error_explanation">
<h2><%= pluralize(event.errors.count, "error") %> prohibited this event from being saved:</h2>
<ul>
<% event.errors.full_messages.each do |msg| %>
<li><%= msg %></li>
<% end %>
</ul>
</div>
<% end %>
<%=f.hidden_field 'timeline_id', :value => current_user.timeline.id %>
<div class="field">
<%= f.label :date %><br />
<%= f.date_select :start_date, :order => [:day, :month, :year], :start_year => 1800 %>
</div>
<div class="field">

<div class="field" id="media_box">

<%= f.text_field :media, :size => 50 %>
</div>
<div class="field">

<%= f.text_area :caption, :size => "47x3" %>
</div>
<div class="actions">

</div>
<% end %>
events / create.js.erb:
$('#new-event').html('<%= escape_javascript( render :partial => "/timelines/new_event", :locals => { :event => Event.new(:timeline_id=>@timeline.id) } ) %>');
$('.notice').html("<p>Event was successfully created.</p>");
$('.notice').show(300);
$('#my-timeline-box').html('<%= escape_javascript( render :partial => "/timelines/my_timeline" ) %>');
$('#show-timeline').html('<%= escape_javascript( render :partial => "/timelines/show_timeline" ) %>');
(下の2行は、タイムライン自体を更新するためのものです)。
