You really should follow my previous advice to work right through
railstutorial.org, including doing all the exercises. That way you will
learn the basics of rails and not need to ask for help with simple problems.

What you're looking for is probably uniqueness check, either at model
level (validates_uniqueness_of) and/or database (unique index).

Here, @n will always be true because you have:

> @n = Box.where(name: params[:name])

which always return trueish value even when there's no result. You need
either call `take` or use `find_by` instead or do it properly as I wrote
above.

Try learning English (for example, using https://id.duolingo.com/ ).

 I'm assuming you want if
@admin.save then a render or
redirect afterwards.
#correct,i assuming here i want input data to db with defference name.
#means:if i have field name with value "cow" on db, i not want not have two 
"cow" name on table Box,because that i use @n as checker,are there name with 
'cow'.'quotes'(i want make sign up with manual but here i assuming def create 
as login for my ask today).
Truely i have 2 controller
1.blog_
2.user_
for this action i assuming that  "def create" on user_ ,than back to my ask.
if @n
render 'new' #'new' method on user_
#why i using 'render'because for flash[:error] ex:sorry that name... & if not 
use than flash no function
else
@admin.save
redirect_to blog_index_path #this routes back to index
#why,because same i using flash
end
---
 Your else
condition should be render new.
#i war tried,but same too.

Re: [Rails] data no same.

[James Jelinek]

In this action you're saying if @n render new which will always render your new 
view in the controller namespace. Then your else is @admin.save

That's why it's not functioning. Depending on what you are trying to do I'm 
assuming you want if @admin.save then a render or redirect afterwards. Your 
else condition should be render new. 

If you can provide some more context and how this should behave I'll be happy 
to help further.
