ruby on rails - FactoryGirls randomly fails with 'Factory not registered', why? -

-

i've tests randomly fail, approx. 20% of times. means without changing code, each time run tests 1 time out of 5 fail "factory not registered" error. it's weird.. :(

this consone output:

failures:    1) unit#new_from_string returns factor metric conversions      failure/error: factorygirl.create :taza      argumenterror:        factory not registered: taza      # ./spec/models/unit_spec.rb:29:in `block (2 levels) in <top (required)>'  finished in 0.29619 seconds 4 examples, 1 failure  failed examples:  rspec ./spec/models/unit_spec.rb:22 # unit#new_from_string returns factor metric conversions  randomized seed 61727

and code:

file: "unit_spec.rb"

require 'spec_helper'  describe unit, "#new_from_string"   "parses string , returns unit object"     [some tests...]      factorygirl.find_definitions     u = factorygirl.create :taza     factorygirl.create :tbsp      [tests...]   end    "returns factor metric conversions"     [tests not involving factory girl...]      # following line 29, fails     factorygirl.create :taza      [tests...]      end end

file "spec/factories/units.rb":

factorygirl.define   factory :taza , :class => customunit     singular 'taza'     plural 'tazas'     physical_type unit::volume     equivalence_factor 200     equivalence_unit 'ml'   end   [other factories...]       end

i think problem on line

factorygirl.find_definitions

actually there no need line when factories in correct directories(i see is), , put gem factory_girl_rails in gemfile.

i think, 20% of time, second test run @ first. @ time, there no definition of factory , test failed. other test has such definition , passed. in other time, first test run first definition exists.

my suggestion:

  1. make sure have factory_girl_rails, not factory_girl in gemfile.
  2. remove line of definition.
  3. [optional recommended] put definition in single file spec/factories , remove other factory files, if don't have factories. easier manage.

i use sonar plugin executes if activated in maven profile. sonar runs on every compile. the problem build fail other team members not have sonar application installed locally. pom.xml checked in team members same copy including sonar configuration, don't want them modify purpose of disabling sonar (they might inadvertently check modified copy in). please advise how configure maven (.m2/settings.xml) and/or pom.xml sonar feature can enabled/disabled local profile. here sonar configuration in each project's pom.xml: <plugin> <groupid>org.codehaus.mojo</groupid> <artifactid>sonar-maven-plugin</artifactid> <version>1.0</version> <executions> <execution> <id>make-sonar</id> <phase>compile</phase> <goals> <goal>sonar</goal> </goals> </execution> </executions> ...

python - TypeError: can only concatenate tuple (not "float") to tuple -

-
i'm new python, question might easy, anyway, patience: as trying call newton-raphson method calculate implied volatility in black-scholes formula call/put option pricing, first thing is, newton method in scipy.optimize seems calculate function's zeros, in black-scholes formula, want function's value option price, not zero. (i'm new here programming, i'm not sure techniques.) should write function things like: def f(sigma, price): return bsformula(s0,k,r,t,q,sigma) - price then, while calling newton method, takes args=() 1 parameter in function, write this: value = newton(bsprice2, 0.5, args=price) but error message: file "bs.py", line 36, in bsimpvol value = newton(bsprice2, 0.5, args=float(price)) file "/usr/lib/python2.7/dist-packages/scipy/optimize/zeros.py", line 143, in newton q0 = func(*((p0,) + args)) typeerror: can concatenate tuple (not "float") tuple could tell me why that? how fix it? apprecia...

this question has answer here: meaning of .this , .class in java 2 answers i'll straight point. im still learning bit of syntax , want know difference between code is code a: public class buttonz extends jbutton{ public buttonz(){ settext(new string(string.valueof(i))); } } please ignore fact i undeclared, not lost. code b: public class buttonz extends jbutton{ public buttonz(){ settext(new string(string.this.charat(i))); } } what don't yet understand difference in typing string.this , string. i under assumption when use dot operator on class accessing it's static methods(and/or variables if they're not hidden). i have studied little bit , have concluded when using string. accessing string static methods.. when using string.this. i'm accessing methods class buttonz extendi...
