cucumber ActiveRecord::ConnectionNotEstablished - activerecord

Question

The exception I am getting is "ActiveRecord::ConnectionNotEstablished: No connection pool for ActiveRecord::Base". I am really on the deep end of the pool (no pun intended) with this one. I really don't understand the connection and connection pool handling, even as much as I have studied this problem. I'm assuming this might be scope related inside of Cucumber, but I do not know. Any and all assistance is appreciated.
Here are the details:
The exception occurs when I perform a count from a Then clause:
WorkTable.where('? is not null',col['COLUMN_NAME']).count
It does not occur if I send the sql directly through the connection:
WorkTable.connection.select_all(st.encode('utf-8')).first['nulls']
My scenario reads as follows:
Scenario: CompanyMaster test for null value
Given table dbo.base_table in stage
Then these columns are expected to be not null
| COLUMN_NAME | nulls |
| id | 0 |
| company_name | 0 |
I establish my class in my env.rb:
class WorkTable < ActiveRecord::Base
end
ActiveRecord::Base.configurations = YAML.load_file(yaml) # yaml is database.yml file name
I establish my connection in a Given clause:
Given(/^table (\w+)\.?([\w_]+) in (\w+)(?: as (\w+))?$/) do |schema,name,env,id|
#sc_name = schema_file_name(schema,name)
WorkTable.logger.info title_line("* Active table(#{#sc_name}) *")
case id
# ActiveRecord::Base.configurations[env]
...
else
WorkTable.table_name = #sc_name
WorkTable.establish_connection(env.to_sym)
# ary = get_tables(WorkTable,schema:schema)
# expect( ary.any?{|s| s.casecmp(name)==0 } ).to eq(true)
end
end
I execute my test in a Then clause:
Then(/^these columns are expected to be not null$/) do |columns|
# expected is an instance of Cucumber::Ast::Table
WorkTable.logger.info title_line('Columns cannot be null')
results = []
columns.hashes.each {|col|
results << {
'COLUMN_NAME' => col['COLUMN_NAME'],
'nulls' => WorkTable.where('? is not null',col['COLUMN_NAME']).count.to_s
}
}
columns.diff!(results,surplus_row: false)
end
It is the WorkTable.where that throws the "ActiveRecord::ConnectionNotEstablished: No connection pool for ActiveRecord::Base". Again, if I use the WorkTable.connection method, I do not get it. Also, it executes fine if I copy all the function code to single ruby script.
I see the following when I "pp WorkTable.connection":
#<ActiveRecord::ConnectionAdapters::SQLServerAdapter version: 4.2.2, mode: dblib, azure: false>
And I see the following when I "pp WorkTable.connection_pool":
#<ActiveRecord::ConnectionAdapters::ConnectionPool:0x42f5238

Ruby 1.9.3, activerecord (4.2.0), activerecord-sqlserver-adapter (4.2.2), and cucumber (1.3.18). And sql server 2014 [this has been a bugger for me].
Thank you for you time and consideration.

== Additional detail ==
Ignore the sql-server reference. I get the same exception when I reconfigure to work with SqLite. So it is not related to db platform.

Check your env.rb, conf in supports, it seems you are making connections in steps, ideally you should do it in before_scenario or before feature file rather than per steps.
It could be possible after steps your connection is not working properly.
