Autocomplete with Vim and Rails Datamapper - ruby-on-rails

Is there a way that I can have auto completion in Vim after I load a model from the database?
So for example if I have a model of type Foo with an instance method of type bar and do the following
foo = Foo.first(:param=>'x')
foo.b
should show me bar as a possible auto complete value. I think that this is somewhat hard to accomplish with dynamic languages and you would probably have to be aware of the datamapper conventions.
Maybe I'm taking the wrong approach and should not be thinking using auto complete because there is an easier way to code?

I don't think it's possible to do semantic completion in VIM. However if you have written the instance name once, you could use the simple auto completion in VIM to avoid typing long names again.

How to deobfuscate this?

I obfuscated this script using some site
But i'm wondering how to deobfuscate it? can someone help me?
i tried using most decompilers and a lot of ways but none has worked
local howtoDEOBFUSCATEthis_Illll='2d2d341be85c64062f4287f90df25edffd08ec003b5d9491e1db542a356f64a488a1015c2a6b6d4596f2fa74fd602d30b0ecb05f4d768cd9b54d8463b39729eb1fe84630c0f8983f1a0087681fe4f2b322450ce07b
something like that for an example.
the whole script: https://pastebin.com/raw/fDGKYrH7
First reformat into a sane layout. a newline before every local and end will do a lot. Then indenting the functions that become visible is pretty easy.
After that use search replace to inline constants. For example: local howtoDEOBFUSCATEthis_IlIlIIlIlIlI=8480; means you can replace every howtoDEOBFUSCATEthis_IlIlIIlIlIlI with 8480. Though be careful about assignments to it. If there are any then it's better to rename the variable something sensible.
If an identifier has no match you can delete the statement.
Eventually you get to functions that are actually used.
Looking at the code it seems to be an interpreter implementation. I believe it's a lua interpreter
Which means that you'll need to verify that and decompile what the interpreter executes.

Rails Custom ActionForm Helper

I do not like the current date helper for action form and would like to replace it with something like the bootstrap datetime control.
I need to know the steps to write a custom actionform helper. I need this because I am looking to make this a modular solution for date/time control that I can use across projects -- and share with the world too, of course.
I am relatively new to ruby/rails and the whole DSL thing... so please try to explain a little of the magic to a long time c/java programmer.

GXT 3.x Custom PropertyEditor / ValueBaseInputCell

I'm trying to write a custom field editor that will translate between Long and String. IE: String representation on screen but field type is a Long.
I've implemented the PropertyEditor (HrMinPropertyEditor) but don't know how to wire it in. My HrMinField is quite clunky as I needed to use a TriggerFieldCell because the generic types inside TextInputCell etc. prevented me from using them.
Do I need to do a subclass of ValueBaseInputCell? That seems strange since my PropertyEditor has all the Long / String conversions. It also looks difficult.
If so, is there a simple example or some documentation I can read?
BTW, my learning project is Maven based and should be easy to fire up if necessary:
svn checkout http://subversion.assembla.com/svn/freshcode_public/learn/gwt/ learn-gwt
cd learn-gwt
mvn gwt:run
Navigate to GXT | Forms | Time Edit
Thanks in advance,
Pete
PS: I've asked this on the Sencha forum too.
You should use method setPropertyEditor from Field class to specify your custom property editor:
HrMinField f = new HrMinField();
f.setPropertyEditor( new HrMinPropertyEditor() );
I managed to come up with a solution using a Converter and a Validator.
The more complete answer is on the Sencha thread.

In rails.vim why do I get "E345 can't find file in path" errors?

I've been learning Ruby/Rails with vim. Tim Pope's rails.vim seems like a really good tool to traverse files with, but I keep getting these pesky "E345 can't find file in path" errors. I'm not vim expert yet, so the solution isn't obvious. Additionally, I've tried this and it doesn't apply to my problem.
As an example of the problem. I have a method format_name defined in app/helpers/application_helper.rb and it is used in app/helpers/messages_helper.rb. Within the latter file I put my cursor over the usage of format_name and then hit gf and I get that error. Similar disfunction with commands like ]f and [f
However, it works sometimes. I was able to gf from user to the app/models/user.rb
Ideas?
I think that is a limitation of rails.vim. It does not support “finding” bare methods. Supporting something like that would require one of the following:
an exhaustive search of all the source files for each “find” request
(which could be expensive with large projects),
“dumb” indexing of method names
(e.g. Exuberant Ctags and gControl-]; see :help g_CTRL-]), or
smart enough parsing of the code to make a good guess where the method might be defined
(which is hard to do properly).
If you know where the method is, you can extend many of the navigation commands with a method name:
:Rhelper application#format_name
But, you do not have to type all of that in. Assuming the cursor is on format_name you can probably just type:RhTabspaceappTab#Control-R Control-W (see :help c_CTRL-R_CTRL-W).

Problems with Netbeans re: Rails erb/rhtml intellisense?

I've been using Netbeans for Rails and like it a lot, considering how little I paid for it. But something that bothers me is that when I'm editing an RHTML or ERB file, it doesn't do the code autocomplete - or at least not reliably. Sometimes it shows the appropriate variables and methods that are available on an object after you type the dot operator. Sometimes it ignores the instance variables. Is there a solution for this? (Please don't say RadRails).
Oh and one more thing in case anyone has solved this: considering how often I have to type <% when I'm in a Rails template, I wish there was some hotkey for autotyping the tag . . . ? I always have to stop and look down at my keyboard to find the < and % keys before I can type the tag so it's not as trivial as it might sound.
I believe you're looking for something like this:
http://ruby.netbeans.org/codetemplates-rhtml.html
Type in one of the triggers, then hit the tab key to expand it to the code as given.
Also, you might want to explore using HAML. It's much easier on the hands.
