Rails - input default value from record

Perhaps I'm being silly but I've been trying to set a default value for an input with ruby on rails for hours and haven't cracked it.

I'm making a partial which can either allow users to create new records but will also show existing records if they exist. Code as follows

<input type="text" <%= (@prices.empty? || @prices.first.name.length == 0) ? 'placeholder="General admission"' : "value=" + @prices.first.name.to_s %> >

Which works perfectly for any value that exists UNLESS there is a space, for example, if price.name = "general admission" OR if price.name = "" (in which case it prints the placeholder) I get the following produced

<input type="text" admission&#39;="" value="'general" id="event_price_name" name="[event][price][0][name]" aria-label="..." class="form-control">

It seems to get tripped up by the space.

Am I trying to use Rails in a way it wasn't designed to be done in? I'm more used to PHP which may be it!

Thanks

You should use the text_field_tag helper to build the input, this is preferred over building it with partial interpolation. Also, placeholder will automatically be overwritten if there is a value so you don't need to handle that part in the code, that's how it behaves by default on the browser. 

<%= text_field_tag :admission, @prices.first.name.to_s, {placeholder: 'General Admission'} %>
