If & else 语句更改 _form.html.erb 中的提交按钮文本 - Rails4
If & else statement to change submit button text in _form.html.erb - Rails4
谁能告诉我这是怎么写的:
文件:views/adverts/_form.html.erb
<% if action: "new" %>
<div class="form-actions">
<%= f.button :submit, 'Post Job' %>
</div>
<% else %>
<div class="form-actions">
<%= f.button :submit, 'Update Job' %>
</div>
<% end %>
您想使用 action_name
。此外,而不是 if/else
使用三元运算符(oneliner):
f.button :submit, action_name == 'new' ? 'Post Job' : 'Update Job'
甚至更短:
<%= f.submit action_name == 'new' ? 'Post Job' : 'Update Job'%>
