[英]Updating Div in Rails without changing view after an update request
I'm new to rails. 我是新手。 I'm using form_for to update a 'collab' database entry.
我正在使用form_for更新'collab'数据库条目。 I've modified my update function to create a new instance variable called "@interpreted_code" and assigned it to a string.
我已经修改了更新功能,以创建一个名为“ @interpreted_code”的新实例变量,并将其分配给一个字符串。 When this variable is created/changed in my update function I'd like the view to display it without a reload.
在更新功能中创建/更改此变量后,我希望视图在不重新加载的情况下显示它。 Here is my view, collab.html.erb
这是我的观点,collab.html.erb
<%= form_for @collab, :remote=>true do |f| %>
<p>
Enter Ruby Code<br>
<%= f.text_area :text %>
</p>
<p>
<%= f.submit %>
</p>
<% end %>
<div id='interpreted' >
<%= @interpreted_code.inspect %> #this doesn't work
</div>
And here is my update function in my controller.rb 这是我controller.rb中的更新功能
def update
@collab = Collab.find(params[:id])
if @collab.update(collab_params)
File.open('rubyfile.rb', 'w') { |file| file.write(@collab.text) }
@interpreted_code = "BLAH BLAH (change later)"
end
render :nothing =>true
end
Try this- 尝试这个-
First create a partial like this _interpreted_code.html.erb 首先创建一个这样的_interpreted_code.html.erb部分
<%= @interpreted_code.inspect %>
Change your view now like this- 现在就这样更改您的视图-
<%= form_for @collab, :remote=>true do |f| %>
<p>
Enter Ruby Code<br>
<%= f.text_area :text %>
</p>
<p>
<%= f.submit %>
</p>
<% end %>
<div id='interpreted' >
<%= render partial: "interpreted_code" %>
</div>
Create file update.js.erb 创建文件update.js.erb
$("#interpreted").html("<%= raw escape_javascript(render(:partial => 'interpreted_code')) %>")
Change your controller like this- 像这样更改您的控制器-
def update
@collab = Collab.find(params[:id])
if @collab.update(collab_params)
File.open('rubyfile.rb', 'w') { |file| file.write(@collab.text) }
@interpreted_code = "BLAH BLAH (change later)"
end
respond_to do |format|
format.js
end
end
