i have the following json template



template.py



from string import Template

test1 = Template(u'''
{
"data": {
"name": "$name"
}
}
''')


and to generate the JSONs I use
JSONGen.py



import template

class JSONGen:
result1 = template.test1.safe_substitute(
name = 'SomeName'
)
print(result1)


now that works, it produces the JSON but i'm trying to create a function that accepts the template name and calls it something like



JSONGenV2.py



import template

class JSONGenV2:

def template_func(self, templateName):
generatedTemplate = template.templateName.safe_substitute(
name = 'SomeName'
)

print (generatedTemplate)

template_func(test1)


now what i want to achieve is to use 'templateName' contents to be the template to call, as it is right now



template.templateName.safe_substitute


gives me an error saying 'templateName' doesn't exist, how can 'templateName' be a changed to the value passed in tihs case 'test1' so it would call



template.test1.safe_substitute


Thank you

    That is not a safe way to generate JSON. The "safe" in the method name doesn't mean that.

Use getattr(), usage like this:




getattr(object, name[, default])



Return the value of the named attribute of object. name must be a string. If the string is the name of one of the object’s attributes, the result is the value of that attribute. For example, getattr(x, 'foobar') is equivalent to x.foobar. If the named attribute does not exist, default is returned if provided, otherwise AttributeError is raised.




Applied to your code:



class JSONGenV2:

def template_func(self, templateName):
generatedTemplate = getattr(template, templateName).safe_substitute(
name = 'SomeName'
)

print (generatedTemplate)

template_func(test1)

You need a way to convert a template name to instance of the actual template.

I would define a dictionary with the keys being the template name, and value being the template instance.



test1 = Template(...)
test2 = Template(...)
templates = {
'test1': test1
'test2': test2
}


Now in your method you could use the templates dictionary to get the instance of the template you requested:



def template_func(self, templateName):
generatedTemplate = templates[templateName].safe_substitute(
name = 'SomeName'
)
print (generatedTemplate)


And you would call the method like so: template_func('test1')

    You need a way to convert a template name to instance of the actual template.

    I would define a dictionary with the keys being the template name, and value being the template instance.



    test1 = Template(...)
    test2 = Template(...)
    templates = {
    'test1': test1
    'test2': test2
    }


    Now in your method you could use the templates dictionary to get the instance of the template you requested:



    def template_func(self, templateName):
    generatedTemplate = templates[templateName].safe_substitute(
    name = 'SomeName'
    )
    print (generatedTemplate)


    And you would call the method like so: template_func('test1')
