Using simple_form_for, Bootstrap and Rails 3. In a form: <%= f.input :upload, label: 'PDF file:' , input_html: {accept: ('application/pdf') } %> I don't know how I'd style this so that the "choose file" button can have a different class ('btn btn-primary'). Additionally, when using with Bootstrap at least, its severely misaligned by default. See attached image. Finally, how do I redefine the text from "No file chosen" to "Chose file" when there isn't one added yet, and show the file name when there is one. This is how I do it: In the view add your form file field and hide it Add a styled

阅读更多关于 Rails: Using simple_form and integrating Twitter Bootstrap

I'm trying to build a rails app and simple_form looks to be a really useful gem. Problem is that I am using twitter bootstrap css to do the styling and the simple_form doesn't allow you to specify the layout of the html.

Note: This answer only applies to SimpleForm < 2.0 Start with this in config/initializers/simple_form.rb : SimpleForm.form_class = nil SimpleForm.wrapper_class = 'clearfix' SimpleForm.wrapper_error_class = 'error' SimpleForm.error_class = 'help-inline' Then there's space missing

问题 I have a model named Book , and I want to adjust the standard Book#new to show the fields for 10 books, so that 10 can be created at once instead of just one. I looked at this question and found that I could repeat the form if I added 10.times to my form. However, I didn't do it correctly because a new record is saved, but with all fields null. What I want to do is to: Allow the user to enter up to 10 books at one-time and then save them If the user populates only three book records, create
