ruby on rails - Using Formtastic to select from a radio set and optionally create a new record -

-

I have started using Forsterstastic in the last two days and have come in my first head-scratcher.

I am working with items that have some related accounts of each. In the question in the page, you will have to choose a payee account, this can be either an account we already know. ("Main contact") or a new account which you can create by filing short information.

I'm trying to replicate this design:

Using Formattic is very easy to display a form to enter information for a new account. is. 

  & lt;% = form.inputs: street ,: city ,: = & gt; : Address% & gt;

It is also very easy to create a radio selection list of available accounts. 

  & lt;% = form.input: address ,: as = & gt; : Radio ,: collection = & gt; @ Address% & gt;

As the picture above, I'm worried about the problem, how to do both - select an existing account or create a new one.

Okay, the real question is how to do both beauty What I thought I think is adding the argument to the controller and I suspect that there is a beautiful solution that I I'm not seeing (recently dipping into the ROR, it's a very familiar sense).

Can not see a solution that does not add some rows to a controller. Although "fat model, thin controller" is a good principle, it is not always possible to have "one-liner" methodical methods, as well as for the scenes the variable is filtered before setting it up.

So what's the "level of beauty" about which we are talking about? ;) Maybe you can post the solution you think and other members will comment on or rate it?

Obfuscating Python code? -

I'm looking for a way to hide my Python source code. print "Hello World!" How can I encode this example so that it is not human-readable? I have been asked to use Base 64 but I'm not sure how. itemprop = "text"> It is limited only, first level ambiguous resolution, but has built-in: byte-code in Python Is a compiler for: dragon-o-m py_compile & lt; Your program.py & gt; creates a .pyo file with a byte-code, and where the docstrings are removed, etc. You can rename .pyo with the .py extension, and python & lt; Your program.py & gt; runs as your program, but it does not have your source code. PS : If your program blur modules like this, you need to rename them with the .pyc suffix (I Not sure it will not break a day), or you can work with .pyo and run them with python -o ... .pyo ( Import should work). This will allow dragon to search your modules (otherwise, Python looks for the .py module).
