Any ideas on how to convert this CSV into a ruby array using vim?
Starting CSV:
Year,Make,Model
1997,Ford,E350
2000,Mercury,Cougar
Desired Array:
car_info = [
{'Year' => '1997', 'Make' => 'Ford', 'Model' => 'E350'},
{'Year' => '2000', 'Make' => 'Mercury', 'Model' => 'Cougar'},
]
I have > 2000 entries like the CSV above, and I'd love a way to quickly re-format it for use in my Rails app. I'd like to use vim, but I'm open to other options too.
FasterCSV.read("path/to/file.csv", :headers => true).map do |row|
{ "Year" => row[0], "Make" => row[1], "Model" => row[2] }
end
PS: Install faster_csv gem
In vim, you can use global search and replace with a regular expression:
:g/\(.*\),\(.*\),\(.*\)/s//{'Year' => '\1', 'Make' => '\2', 'Model' => '\3'}/g
Then edit the first and last lines of the resulting file accordingly.

I have this csv structure
"CATEGORY";"NAME";"AGE"
"Red";"John";"34"
When I import the file through smarter_csv gem I get this hash
{:"\"CATEGORY\""=>"\"Red\"", :"\"NAME\""=>"\"John\"", :"\"AGE\""=>"\"34\""}
The code I use is the following
options = {:col_sep => ";",:row_sep => :auto, :quote_char => "\x00"}
SmarterCSV.process(save_folder, options) do |array|
Item.create(array.first)
end
What puzzles me is the \" that is added in each item of the hash. I have used this same method before without issues and I don't understand what is going wrong, but the expected hash should be plan text with no backslash and additional quotes.
As a note, is I don't use the ";quote_char => "\x00"" option I get a malformed csv error.
This works out of the box, but the quote_char you chose was incorrect; it should be '"', which is the default setting.
require 'smarter_csv'
SmarterCSV::VERSION
=> "1.2.3"
data = SmarterCSV.process('/tmp/test.csv', {:col_sep => ";"})
=> [{:category=>"Red", :name=>"John", :age=>34}]
# or like this:
data = SmarterCSV.process('/tmp/test.csv', {
:col_sep => ";",:row_sep => :auto, :quote_char => '"'
})
=> [{:category=>"Red", :name=>"John", :age=>34}]
I'm upgrading spree to from spree 1.0 to 1.3 and get stuck with the new currency options.
I want to render prices as: '€ 100' but instead get '€100'. How do I get a space between the unit and the value?
Note: Changing the locale file doesn't work, since it uses the money gem.
There are a bunch of ways to do this. The easiest would probably be to re-register the Euro currency with a different symbol.
Put the following in an initializer:
# encoding: utf-8
Money::Currency.register({
:priority => 1,
:iso_code => "EUR",
:iso_numeric => "978",
:name => "Euro",
:symbol => "€ ",
:subunit => "Cent",
:subunit_to_unit => 100,
:separator => ".",
:delimiter => ","
})
A rails console now reports:
> Spree::Money.new(100, currency: 'EUR')
=> € 100.00
I did the following in my config/initializers/spree.rb to inject a different symbol:
Money::Currency.table[:chf].merge!(symbol: 'CHF ')
This way the currencies aren't going to mix up.
Thanks a lot.
In my case, used the following to change the symbol generated by the to_html method, in case anyone has the same problem.
# encoding: utf-8
Money::Currency.register({
:priority => 1,
:iso_code => "CLP",
:iso_numeric => "152",
:name => "Chilean Peso",
:symbol => "$",
:subunit => "Peso",
:subunit_to_unit => 1,
:separator => ",",
:delimiter => ".",
html_entity: "$"
})
I solved the problem with the following in an initializer, e.g. config/initializers/currency_formatting.rb:
# Display prices with a space between symbol and number:
Spree::Money.default_formatting_rules[:symbol_before_without_space] = false
This hooks into the formatting rules found in Spree::Money, which can control all the formatting Options of the Money Gem, including the one placing a space between the symbol and the number. This has the advantage over the other solutions presented here that it works with all currencies at once.
Okay, this was pretty easy. As of gem version money(6.16.0).
In Spree intializer spree.rb Recommended way:
Spree.config do |config|
...
...
# Below is deprecated
Spree::Money.default_formatting_rules[:symbol_before_without_space] = false
# Instead try this
Spree::Money.default_formatting_rules[:format] = '%u %n'
end
I am trying to upload my csv data to my sqlite table, this is my code:
require 'csv'
CSV.open('history.csv', 'r') do |row|
HistoryYear.create(:year => row[1], :first => row[2], :second => row[3], :third => row[4], :regular_season_champ => row[5])
end
I am receiving an error message, NoMethodError: undefined method '[]' for #<CSV:0x3c1fe18>. I am a new to Rails and programming in general and cannot seem to find the answer.
You need to use CSV.foreach(file...) instead
You can do something like:
require 'csv'
CSV.foreach('history.csv') do |row|
HistoryYear.create(:year => row[1], :first => row[2], :second => row[3], :third => row[4], :regular_season_champ => row[5])
end
Check out http://www.ruby-doc.org/stdlib-1.9.3/libdoc/csv/rdoc/CSV.html
Also don't forget that arrays (the rows in this case) are 0 indexed i.e. the first element of the row is row[0].
I am attempting to write a ruby on rails app that posts an item to eBay. Cody Fauser/Garry Tan have a gem called ebayApi which is built on top of the ebay gem. When I attempt to post an item, I am getting an error back from ebay that says the condition ID is required for this category. I have found a category that does not require the condition, and I can post to that category. Searching through the eBay API documentation, I have found a tag conditionID under the "item" class. However, in the documentation for ebayAPI, there is no such tag. Looking back at the ebay API documentation, there is an older way to specify condition, using lookup_attributes. I have noted that the return xml is coming in API version 745, and Garry Gan's updated of the ruby interface is running version 609. I have tried using the lookup, and seem to get the same error (condition required). I am using the following code to specify the item:
#ebay = Ebay::Api.new :auth_token => #seller.ebay_token
item = Ebay::Types::Item.new( :primary_category => Ebay::Types::Category.new(:category_id => #ebayTemplate.categoryID),
:title => #ebayTemplate.name,
:description => #ebayTemplate.description,
:location => #ebayTemplate.location,
:start_price => Money.new((#ebayTemplate.startPrice*100).to_d, #ebayTemplate.currency),
:quantity => 1,
:listing_duration => #ebayTemplate.listingDuration,
:country => #ebayTemplate.country,
:currency => #ebayTemplate.currency,
:payment_methods => ['VisaMC', 'PayPal'],
:paypal_email_address => '********#gmail.com',
:dispatch_time_max => 3,
:lookup_attributes => [Ebay::Types::LookupAttribute.new( :name => "Condition", :value => "New")],
# :attribute_sets => [
# Ebay::Types::AttributeSet.new(
# :attribute_set_id => 2919,
# :attributes => [
# Ebay::Types::Attribute.new(
# :attribute_id => 10244,
# :values => [ Ebay::Types::Val.new(:value_id => 10425) ]
# )
# ]
# )
# ],
:shipping_details => Ebay::Types::ShippingDetails.new(
:shipping_service_options => [
# ShippingServiceOptions.new(
# :shipping_service_priority => 2, # Display priority in the listing
# :shipping_service => 'UPSNextDay',
# :shipping_service_cost => Money.new(1000, 'USD'),
# :shipping_surcharge => Money.new(299, 'USD')
# ),
Ebay::Types::ShippingServiceOptions.new(
:shipping_service_priority => 1, # Display priority in the listing
:shipping_service => #ebayTemplate.shipSvc,
:shipping_service_cost => Money.new((#ebayTemplate.shipSvcCost*100).to_d, #ebayTemplate.currency),
:shipping_surcharge => Money.new((#ebayTemplate.shipSurcharge*100).to_d, #ebayTemplate.currency)
)
],
:international_shipping_service_options => [
Ebay::Types::InternationalShippingServiceOptions.new(
:shipping_service => 'USPSPriorityMailInternational',
:shipping_service_cost => Money.new((#ebayTemplate.shipSvcCost*100).to_d, #ebayTemplate.currency),
:shipping_service_priority => 2,
:ship_to_location => #ebayTemplate.shipToLocation
)
]
),
:return_policy => Ebay::Types::ReturnPolicy.new (
:description => 'this product for suckers only!',
:returns_accepted_option => 'ReturnsAccepted'
)
#:condition_id => 1000
)
#response = #ebay.add_item(:item => item)
As you can see, it is just a mutation of the example given by Cody Fauser. The condition_id at the bottom will bring up an error as there is no such attribute. It seems to me there is no facility for this in the gem since the requirement came into existence after the gem was created. I have not been able to find any other gems to connect with ebay. I have also noticed, there are very little complaints about this even though people are still downloading the gem (10 people downloaded it today). I think there are quite a number of people writing for ebay. Is there a key word I am missing to specify the condition? A work around that people have been using? Another gem I have missed?
There is an existing item_conditions_codes.rb in the gem's type directory and only has two values New and Used. Guess you could add more values in there. However still needs mapping to ID's per the updating (and changed from Attributes) method
You have to modify in the gem library in .. ruby/1.8/gems/ebayapi-0.12.0/lib/ebay/types/item.rb
and add the following new lines
# added to allow ConditionID to be pushed into XML
numeric_node :condition_id, 'ConditionID', :optional => true
then in your ruby ebay code use the following convention
:condition_id => 1500,
At least that seems to work for me right now.
I have a CSV file formatted just like this:
name,color,tasty,qty
apple,red,true,3
orange,orange,false,4
pear,greenish-yellowish,true,1
As you can see, each column in the Ruby OO world represents a mix of types -- string, string, boolean, int.
Now, ultimately, I want to parse each line in the file, determine the appropriate type, and insert that row into a database via a Rails migration. For ex:
Fruit.create(:name => 'apple', :color => 'red', :tasty => true, :qty => 3)
Help!
For Ruby 1.8:
require 'fastercsv'
FasterCSV.parse(my_string, :headers => true) do |row|
Fruit.create!(
:name => row['name'],
:color => row['color'],
:tasty => row['tasty'] == 'true',
:qty => row['qty].to_i
)
end
For Ruby 1.9, just rename FasterCSV to CSV and fastercsv to csv:
require 'csv'
CSV.parse(my_string, :headers => true) do |row|
# same as ruby-1.8
end
