I am passing these parameters to a controller:
{
"utf8" => "✓",
"authenticity_token" => "ersjaJ4/ieZelVifP/YpBHTJtiQ53HgO5KYjEdW0BlQ=",
"transaction" => {
"use_balance" => "1",
"traces_attributes" => {
"trace_ids" => ["6"],
"6" => {
"amount" => "12.0",
"charge_id" => "6"
}
},
"positive_balance" => "12",
"property_id" => "2",
"community_id" => "1"
},
"commit" => "Save Payment",
"community_id" => "1",
"property_id" => "2"
}
The controller#create then:
#payment = Transaction.new(params[:transaction])
Then the Transaction model:
belongs_to :property
belongs_to :community
attr_accessible :positive_balance
def traces_attributes=(params)
#INSIDE HERE THE VALUES OF
#params[:trace_ids] => ['6'] OK
#BUT
#self.possitive_balance => "" **NOT OK**
#self.property_id => nil **NOT OK**
end
My hypothesis is that traces_attribute= is executed before positive_balance= and property_id
Can I change this?
Why is this failing?
The order of the assignments should be the same as the order of the params in the form, but I don't think this is guaranteed.
A safer solution would be to only store the data in the traces_attributes= method, and access the other attributes later, for example in a before_save callback.
it looks based on the transaction hash that the property_id is outside of that hash so if you are building based on transactions it won't have a property_id
"transaction"=>{"use_balance"=>"1",
"traces_attributes"=>{"trace_ids"=>["6"],
"6"=>{"amount"=>"12.0",
"charge_id"=>"6"
}
},
"positive_balance"=>"12",
"property_id"=>"2",
"community_id"=>"1"
},
"commit"=>"Save Payment",
"community_id"=>"1",
"property_id"=>"2"}
do you see what i mean, the number of curly braces is messed up and prop. id isn't ending up in transactions ( i just copy and pasted your code pasted above )

I have a huge array full of a bunch of hashes. What I need to do is single out one index hash from the array that meets a specific criteria. (doing this due to an rspec test, but having trouble singling out one of them)
My array is like this
[
{
"name" => "jon doe",
"team" => "team2",
"price" => 2000,
"eligibility_settings" => {}
},
{
"name" => "jonny doe",
"team" => "team1",
"value" => 2000,
"eligibility_settings" => {
"player_gender" => male,
"player_max_age" => 26,
"player_min_age" => 23,
"established_union_only" => true
}
},
{
"name" => "jonni doe",
"team" => "team3",
"price" => 2000,
"eligibility_settings" => {}
},
]
I need to single out the second one, based on its eligibility settings. I just took three of them from my array, have lots more, so simple active record methods like (hash.second) won't work in this instance.
I've tried things like
players.team.map(&:hash).find{ |x| x[ 'eligibility_settings?' ] == true}
However when I try this, I get a nil response. (which is odd)
I've also looked into using the ruby detect method, which hasn't gotten me anywhere either
Players.team.map(&:hash).['hash.seligibiltiy_settings'].detect { true }
Would anybody have any idea what to do with this one?
Notes
players.team.map(&:hash).find{ |x| x[ 'eligibility_settings?' ] == true}
Players.team.map(&:hash).['hash.seligibiltiy_settings'].detect { true }
Is is players or Players ?
Why is it plural?
If you can call map on team, it probably should be plural
Why do you convert to a hash?
eligibility_settings? isn't a key in your hash. eligibility_settings is
eligibility_settings can be a hash, but it cannot be true
If you want to check if it isn't empty, use !h['eligibility_settings'].empty?
Possible solution
You could use :
data = [
{
'name' => 'jon doe',
'team' => 'team2',
'price' => 2000,
'eligibility_settings' => {}
},
{
'name' => 'jonny doe',
'team' => 'team1',
'value' => 2000,
'eligibility_settings' => {
'player_gender' => 'male',
'player_max_age' => 26,
'player_min_age' => 23,
'established_union_only' => true
}
},
{
'name' => 'jonni doe',
'team' => 'team3',
'price' => 2000,
'eligibility_settings' => {}
}
]
p data.find { |h| !h['eligibility_settings'].empty? }
# {"name"=>"jonny doe", "team"=>"team1", "value"=>2000, "eligibility_settings"=>{"player_gender"=>"male", "player_max_age"=>26, "player_min_age"=>23, "established_union_only"=>true}}
If h['eligibility_settings'] can be nil, you can use :
data.find { |h| !h['eligibility_settings'].blank? }
or
data.find { |h| h['eligibility_settings'].present? }
I'm witnessing an odd behavior in Rails, when sending a post request, with the following body:
If you check is a Hash (converted to JSON when sending). But ODDLY when being read by params in controller, is recognized like this:
If you check carefully, the attributes of :first_name and :email are moved to the previous item in the array.
I'd thought if you have an array with certain attributes on the first item, but some different attributes on the following items, the array would be respecting the positions of which the attributes are set for.
I know most likely the answer would be "just put a nil or empty value of those attributes on the first item of the array", but I'm more interested in the reason of why this is happening.
Thank you.
UPDATE
Thanks to a question, I replicated the scenario form a browser (I was originally doing the request from the test feature of rails), and checking the Network from the browser, this is what is being sent:
{
"name": "un nombre",
"team_members": [
{
"user_id": 1,
"team_member_role_id": 4
},
{
"email": "cpamerica#avengers.com",
"first_name": "Cap America",
"team_member_role_id": 4,
"admin": true
},
{
"email": "hulk#avenrgers.com",
"first_name": "Bruce Banner",
"team_member_role_id": 1,
"admin": false
},
{
"email": "ironman#avengers.com",
"first_name": "Tony Stark",
"team_member_role_id": 1,
"admin": false
},
{
"email": "thor#avengers.com",
"first_name": "Thor Hijo de Odín",
"team_member_role_id": 2,
"admin": false
}
]
}
And it works. So I focused on how I was sending the info from the test environment, this is the actual code:
team = {
:name => 'un nombre',
:team_members => [
{
:user_id => 1,
:team_member_role_id => TeamMemberRole.role_communicator_id
},
{
:email => 'cpamerica#avengers.com',
:first_name => 'Cap America',
:team_member_role_id => TeamMemberRole.role_communicator_id,
:admin => true
},
{
:email => 'hulk#avenrgers.com',
:first_name => 'Bruce Banner',
:team_member_role_id => TeamMemberRole.role_visionary_id,
:admin => false
},
{
:email => 'ironman#avengers.com',
:first_name => 'Tony Stark',
:team_member_role_id => TeamMemberRole.role_visionary_id,
:admin => false
},
{
:email => 'thor#avengers.com',
:first_name => 'Thor Hijo de Odín',
:team_member_role_id => TeamMemberRole.role_developer_id,
:admin => false
}
]
}
post create_team_path, :team => team, :format => :json
And what is being read in the controller by request.raw, this is what is getting (using the debugger):
team[name]=un+nombre&
team[team_members][][user_id]=1&
team[team_members][][team_member_role_id]=4&
team[team_members][][email]=cpamerica%40avengers.com&
team[team_members][][first_name]=Cap+America&
team[team_members][][team_member_role_id]=4&
team[team_members][][admin]=true&
team[team_members][][email]=hulk%40avenrgers.com&
team[team_members][][first_name]=Bruce+Banner&
team[team_members][][team_member_role_id]=1&
team[team_members][][admin]=false&
team[team_members][][email]=ironman%40avengers.com&
team[team_members][][first_name]=Tony+Stark&
team[team_members][][team_member_role_id]=1&
team[team_members][][admin]=false&
team[team_members][][email]=thor%40avengers.com&
team[team_members][][first_name]=Thor+Hijo+de+Od%C3%ADn&
team[team_members][][team_member_role_id]=2&
team[team_members][][admin]=false&
format=json
Any idea on why the index of each team_member is missing? Am I sending the array wrong?
To send an acceptable json request you need to send as a formed String instead the hash, also add the headers
your code must look something like this:
post create_team_path, {:team => team}.to_json, 'CONTENT_TYPE' => 'application/json;charset=utf-8'
Note the problem is within the parser hash to form-request not adding the index of each object

I have model LoanPlan and Career, they are associated by a join_table
The request params from another frontend developer will be like this
"loan_plan" => {
"id" => 32,
"careers" => [
[0] {
"id" => 8,
},
[1] {
"id" => 9,
}
]
},
However, I got ActiveRecord::AssociationTypeMismatch: Career(#70198754219580) expected, got ActionController::Parameters(#70198701106200) in the update method
def update
#loan_plan.update(loan_plan_params)
end
When I tried to update the loan_plan model with careers params, it expects the params["careers"] should be careers object of a array instead of ids of a array.
So my workround is to manually fectch the careers objects of a array and replace the sanitized params.
It seems dirty and smells bad, any better solution in Rails way? Thanks
def loan_plan_params
# params.fetch(:loan_plan, {})
cleaned_params = params.require(:loan_plan).permit(
:id,
:name,
{:careers=>:id}
)
cleaned_params["careers"] = Career.find(cleaned_params["careers"].map{|t| t["id"]})
cleaned_params
end
model
class LoanPlan < ActiveRecord::Base
has_and_belongs_to_many :careers
accepts_nested_attributes_for :careers
end
In Rails way, params should be
"loan_plan" => {
"id" => "32",
"career_ids" => ["8", "9"]
}
and the strong parameter loan_plan_params should be
def loan_plan_params
params.require(:loan_plan).permit(
:id,
:name,
:career_ids => []
)
end
i have two fields in my model and i want add them in Soulmate::Loader:
for example, my "person" model has name and email field. and i want load then in Soulmate:
loader = Soulmate::Loader.new("people")
loader.add("term" => name, "id" => self.id, "data" => {
"link" => Rails.application.routes.url_helpers.person_path(self)
})
i want add name and email in loader.add. but i can't.
def load_into_soulmate
loader = Soulmate::Loader.new("people")
loader.add("term" =>{ name , email }, "id" => self.id, "data" => {
"link" => Rails.application.routes.url_helpers.person_path(self)
})
end
and
def load_into_soulmate
loader = Soulmate::Loader.new("people")
loader.add("term" =>{ "name" => name ,"email" => email }, "id" => self.id, "data" => {
"link" => Rails.application.routes.url_helpers.person_path(self)
})
end
error show when i use Person.find_each(&:save) for add datas to redis:
ArgumentError: ArgumentError
from /var/lib/gems/2.2.0/gems/soulmate-1.1.0/lib/soulmate/loader.rb:31:in `add'
but all is wrong.
I think you have to use aliases.
def load_into_soulmate
loader = Soulmate::Loader.new("people")
loader.add("term" =>"name", "id" => self.id, "aliases" => [email], "data" => {
"link" => Rails.application.routes.url_helpers.person_path(self)
})
end
In my rails application, I have a button which when clicked, copies data from one database and insert it in another.
I am using octopus gem to link my application to 2 databases.
To copy a record from db_A to db_B, I am using the code below:
Octopus.using(:shard_B) do
#book_new_live = Book.create(
:BK_SUB_FK => #book.BK_SUB_FK,
:BK_TITLE => #book.BK_TITLE,
:BK_SOURCE => "",
:BK_PUB => "",
:BK_COVER => "",
:BK_LABEL_PRODUCT => #book.BK_LABEL_PRODUCT,
:BK_FINAL_LABEL => "",
:BK_VISUAL_METHOD => #book.PRB_VISUAL_METHOD,
:BK_DB => "",
:BK_COVERED_REGION => "",
:BK_VERSION_NO => #book.BK_VERSION_NO,
:BK_SEQ_FILE => "",
)do |primary|
primary.BK_ID = #book.BK_ID
end
end
Database 'db_b', to which data in copied, does not accept null values and the columns cannot be null and the default value is 'NONE'.
Also, I am not allowed to modify the structure of the database so that it can accept null values.
If I use the simplified code below, I get an error message which informs me that the columns 'BK_SOURCE', 'BK_PUB', 'BK_COVER'...cannot be null. By default rails is passing null to those columns.
So I have to pass empty strings to the columns which cannot be null.
Octopus.using(:shard_B) do
#book_new_live = Book.create(
:BK_SUB_FK => #book.BK_SUB_FK,
:BK_TITLE => #book.BK_TITLE,
:BK_LABEL_PRODUCT => #book.BK_LABEL_PRODUCT,
:BK_VISUAL_METHOD => #book.PRB_VISUAL_METHOD,
:BK_VERSION_NO => #book.BK_VERSION_NO,
)do |primary|
primary.BK_ID = #book.BK_ID
end
end
Is there a way of preventing rails from passing null values to the columns not mentioned in the above code?
If i understand you correctly, you can just use the or operator to send your values like this:
Octopus.using(:shard_B) do
#book_new_live = Book.create(
:BK_SUB_FK => #book.BK_SUB_FK,
:BK_TITLE => #book.BK_TITLE,
:BK_SOURCE => #book.BK_SOURCE || "NONE",
:BK_PUB => #book.BK_PUB || "NONE",
:BK_COVER => #book.BK_COVER || "NONE",
:BK_LABEL_PRODUCT => #book.BK_LABEL_PRODUCT,
:BK_FINAL_LABEL => "",
:BK_VISUAL_METHOD => #book.PRB_VISUAL_METHOD,
:BK_DB => "",
:BK_COVERED_REGION => "",
:BK_VERSION_NO => #book.BK_VERSION_NO,
:BK_SEQ_FILE => "",
)do |primary|
primary.BK_ID = #book.BK_ID
end
end
By saying that the value to be passed is #book.BK_SOURCE || "NONE", if the attribute is nil, then the string NONE is passed instead.
EDIT
hash = {
:BK_SUB_FK => #book.BK_SUB_FK,
:BK_TITLE => #book.BK_TITLE,
:BK_SOURCE => #book.BK_SOURCE,
:BK_PUB => #book.BK_PUB,
:BK_COVER => #book.BK_COVER,
:BK_LABEL_PRODUCT => #book.BK_LABEL_PRODUCT,
:BK_FINAL_LABEL => #book.BK_FINAL_LABEL,
:BK_VISUAL_METHOD => #book.PRB_VISUAL_METHOD,
:BK_DB => #book.BK_DB,
:BK_VERSION_NO => #book.BK_VERSION_NO
}
hash = hash.delete_if { |k, v| v.nil? }
Octopus.using(:shard_B) do
#book_new_live = Book.create(hash)do |primary|
primary.BK_ID = #book.BK_ID
end
end
Give it a try.
