小编Pat*_*ick的帖子

1. 以下是README和示例:https://github.com/gruntjs/grunt-contrib-copy/blob/master/README.md.
2. 以下是https://github.com/gruntjs/grunt-contrib-copy/blob/master/tasks/copy.js代码的相关部分(我显然无法理解):

module.exports = function(grunt) {
  'use strict';

  var path = require('path');

  grunt.registerMultiTask('copy', 'Copy files.', function() {
    var kindOf = grunt.util.kindOf;

    var options = this.options({
      processContent: false,
      processContentExclude: []
    });

    var copyOptions = {
      process: options.processContent,
      noProcess: options.processContentExclude
    };

    grunt.verbose.writeflags(options, 'Options');

    var dest;
    var isExpandedPair;
    var tally = {
      dirs: 0,
      files: 0
    };

    this.files.forEach(function(filePair) {
      isExpandedPair = filePair.orig.expand || false;

      filePair.src.forEach(function(src) {
        if (detectDestType(filePair.dest) === 'directory') {
          dest = (isExpandedPair) ? filePair.dest : …

Factory Boy弃用了set_creation_function(参见ChangeLog 2.6.1)并建议开发人员

使用SomeFactory的_create()方法的替换替换factory.set_creation_function(SomeFactory,creation_function)

我有i)一些衍生工厂类和ii)我的数据库会话在另一个模块中实例化,所以我尝试用下面的第二个代码块替换https://github.com/mattupstate/overholt中的工作示例.PyCharm警告我"db"导入没有被使用,所以我怀疑在设置sqlalchemy_session时可能没有正确解除引用？

使用nosetests 1.3.7(但现在不推荐使用FactoryBoy的set_creation_function):

from myapp.core import db

def create_sqlalchemy_model_function(class_to_create, *args, **kwargs):
    entity = class_to_create(**kwargs)
    db.session.add(entity)
    db.session.commit()
    return entity

Factory.set_creation_function(create_sqlalchemy_model_function)

不使用nosetests 2.x(看起来db没有被正确引用？)

from factory.alchemy import SQLAlchemyModelFactory as Factory
from myapp.core import db

class Factory():
    class Meta:
        sqlalchemy_session = db.session

    def _create(cls, model_class, *args, **kwargs):
        entity = model_class(*args, **kwargs)
        db.session.add(entity)
        db.session.commit()
        return entity
