x = {"utf8"=>"✓",
"authenticity_token"=>"xxxxxxxxxxxxx=",
"file"=>#>,
"unit_id"=>"00001"}
I have ruby data structure like this and um trying to get the value of #original_filename field
I tried something like this
x["#original_filename"]
and
x[:original_filename]
But both has thrown me an error . How to access that specified element value?
looks like you're trying to upload a file; from your tiny screenshot maybe you're referring to params[:file].original_filename?
The parameter ["file"] is a ActionDispatch::Http::UploadedFile, which has the original_filename member variable, as you can see in the params displayed in your image or here:
http://api.rubyonrails.org/classes/ActionDispatch/Http/UploadedFile.html
So, the way to get this value would be x["file"].original_filename

I am trying to display product details using javascript. I am using haml and RoR-4.2.1. I have the following code
var a = new Array();
#{#productlist.map do |prdct|
<<-EOS
var t = new Object();
t.product_id = '#{prdct.product_id}';
t.name = '#{prdct.name}';
t.address = '#{prdct.address}';
a.push(t)
EOS
end.join("\n")}
I have a model images which contains the images for the products. A product may or may not have images. So to display images I have added the following
t.shop_image =
"#{if prdct.images.present?
prdct.images.first.image_url
else
''
}"
statements before push statement. But it is generating an issue. How can I add if checking in the heredocs.
Approach 1: do the same thing you'd do with "normal" strings.
"#{product.images.present? ? product.images.first.image_url : ''}"
Approach 1+: extract the expression above into a variable, so that your template contains less logic.
Approach 2: don't abuse heredocs and use ERB instead.

[ERROR] Lua is unable to understand file "darkrp_customthings/jobs.lua" because its author made a mistake around line number 21.
The best help I can give you is this:
There is an opening '(' bracket at line 20, but this bracket is never closed or not closed in time. It was expected to be closed before the '=' at line 21.
Can someone help correct the errors in my code?
The code:
https://www.dropbox.com/s/o2w9jx2kqefu2n0/job%20.txt?dl=0
You wrote something like this (simplified):
TEAM_TERRORIST = AddExtraTeam(
"Terrorist",
customCheck = function(ply) end
)
This is not valid syntax in Lua, where there are no named parameters.
Maybe the AddExtraTeam function expects a table instead? E.g. this is valid syntax:
TEAM_TERRORIST = AddExtraTeam{
"Terrorist",
customCheck = function(ply) end
}
Not sure this is the right solution though, I don't know DarkRP.

im making an app to help students study better but im having trouble. the app let you make notes between other things,but I need a code that can recognize specific characters in a text for example the user writes in a note "Dolphins : are cetacean mammals closely..." i need the app to recognize the character : and also the part thats on the left it needs to be save to use later, as a variable and the part of the right also but as a different variable so I can use them later.
if you can get me the code for that it be great but if possible i preferred a tutorial :)
(the app is for iPhone im using Xcode 5)
Something like:
NSArray *stringArray = [yourNSString componentsSeparatedByString:#":"];
NSString *leftString = stringArray[0];
NSString *rightString = stringArray[1];
EDIT: Just make sure string has the ":" character.

I'm new in delphi and i thought it might be safer to swap object names in loop instead of copying whole block for each object. So I need to use variable name as some objects name.
Here is an example of what i tried and what i am trying to do.
Var
YazGrid: TStringGrid;
I defined a variable for grid name as above and i am trying to use like this:
Some Loop
begin
if a_variable>=10 then
YazGrid:=form1.StringGrid1
else
YazGrid:=form1.StringGrid2;
YazGrid.Cells[1,i] := 'SomeText';
End;
As the result- it comes out with the "Access Violation" error. How should i do this?
Thanks in advance.
Everything looks right in your code.
Make sure that variable "i" in bound. Anyway, even if "i" out-of-bound, this shound't raise Access Violation.
Tested with Delphi XE2 and XE4.
I suppose that error occure in code that not showed in your sample.

I'm collecting size information from my users, so when they view the main products page, they only see products that are available in their size. I think the solution involves product scopes, but I'm not sure how to implement it. Anyone have any ideas on the best way to implement this?
The logic to find the products to display is generally done by:
https://github.com/spree/spree/blob/v2.1.1/core/lib/spree/core/controller_helpers/search.rb#L5-L9
An example of it being used is here:
https://github.com/spree/spree/blob/v2.1.1/frontend/app/controllers/spree/products_controller.rb#L10
By default, it will use this code to find the products
https://github.com/spree/spree/blob/v2.1.1/core/lib/spree/core/search/base.rb#L15-L24
In order to override this, you can override the searcher_class configuration:
https://github.com/spree/spree/blob/v2.1.1/core/app/models/spree/app_configuration.rb#L101-L108
The searcher class has access to the current user, and I'm assuming you've modified the current user to contain their size.
You can do a crazy-ish query to get all products of a certain size. For example:
Spree::Product.joins(:variants_including_master => :option_values)
.where('spree_option_values.presentation = ? AND
spree_option_values.option_type_id = ?', 'XL',
Spree::OptionType.find_by_name('tshirt-size').id)
Replace 'XL' with current_user.size or whatever you have setup, and you should have things working.
Hope that gives you a good place to start.
