使用 PyYaml 将集合转储到 YAML 文件
我正在编写一个 python 应用程序。我正在尝试使用 PyYaml 将 python 对象转储到 yaml 中。我正在使用 Python 2.6 并运行 Ubuntu Lucid 10.04。我在 Ubuntu 包中使用 PyYAML 包: http://packages.ubuntu.com/ lucid/python/python-yaml
我的对象有 3 个文本变量和一个对象列表。大致是这样的:
ClassToDump:
#3 text variables
text_variable_1
text_variable_2
text_variable_3
#a list of AnotherObjectsClass instances
list_of_another_objects = [object1,object2,object3]
AnotherObjectsClass:
text_variable_1
text_variable_2
text_variable_3
我想要转储的类包含 AnotherObjectClass 实例的列表。这个类有一些文本变量。
PyYaml 不知何故不会转储 AnotherObjectClass 实例中的集合。 PyYAML 确实转储 text_variable_1、text_variable_2 和 text_variable_3。
我正在使用以下 pyYaml API 转储 ClassToDump 实例:
classToDump = ClassToDump();
yaml.dump(ClassToDump,yaml_file_to_dump)
有人有将对象列表转储到 YAML 的经验吗?
这是实际的完整代码片段:
def write_config(file_path,class_to_dump):
config_file = open(file_path,'w');
yaml.dump(class_to_dump,config_file);
def dump_objects():
rule = Miranda.Rule();
rule.rule_condition = Miranda.ALL
rule.rule_setting = ruleSetting
rule.rule_subjects.append(rule1)
rule.rule_subjects.append(rule2)
rule.rule_verb = ruleVerb
write_config(rule ,'./config.yaml');
这是输出:
!!python/object:Miranda.Rule 规则条件:全部 规则设置:!!python/object:Miranda.RuleSetting {confirm_action: true,描述:我的 配置,启用:true,递归:true,source_folder:source_folder} Rule_verb: !!python/object:Miranda.RuleVerb {压缩: true, dest_folder: /home/zainul/Downloads, 类型:移动文件}
I am writing a python application. I am trying to dump my python object into yaml using PyYaml. I am using Python 2.6 and running Ubuntu Lucid 10.04. I am using the PyYAML package in Ubuntu Package: http://packages.ubuntu.com/lucid/python/python-yaml
My object has 3 text variables and a list of objects. Roughly it is something like this:
ClassToDump:
#3 text variables
text_variable_1
text_variable_2
text_variable_3
#a list of AnotherObjectsClass instances
list_of_another_objects = [object1,object2,object3]
AnotherObjectsClass:
text_variable_1
text_variable_2
text_variable_3
The class that I want to dump contains a list of AnotherObjectClass instances. This class has a few text variables.
PyYaml somehow does not dump the collections in AnotherObjectClass instance. PyYAML does dump text_variable_1, text_variable_2, and text_variable_3.
I am using the following pyYaml API to dump ClassToDump instance:
classToDump = ClassToDump();
yaml.dump(ClassToDump,yaml_file_to_dump)
Does any one has any experience with dumping a list of objects into YAML ?
Here is the actual full code snippet:
def write_config(file_path,class_to_dump):
config_file = open(file_path,'w');
yaml.dump(class_to_dump,config_file);
def dump_objects():
rule = Miranda.Rule();
rule.rule_condition = Miranda.ALL
rule.rule_setting = ruleSetting
rule.rule_subjects.append(rule1)
rule.rule_subjects.append(rule2)
rule.rule_verb = ruleVerb
write_config(rule ,'./config.yaml');
This is the output :
!!python/object:Miranda.Rule
rule_condition: ALL
rule_setting: !!python/object:Miranda.RuleSetting {confirm_action: true, description: My
Configuration, enabled: true, recursive: true, source_folder: source_folder}
rule_verb: !!python/object:Miranda.RuleVerb {compression: true, dest_folder: /home/zainul/Downloads,
type: Move File}
