Not able to create a SOAP filter in suds

问题:

I have a SOAP request that takes below XML body

ProductsIditemName2.0ONETIME

I can make a successful request using Boomerang.

Now I actually want to use it in my python code. So I tried,

inputElement = client.factory.create('CreateExportJobRequest')  inputElement.ExportJobTypeName = "Products" inputElement.ExportColumns.ExportColumn = ["Id", "itemName"]  inputElement.Frequency = 'ONETIME'  if updatedSince:     inputElement.ExportFilters.ExportFilter = ['updatedSince']  t = client.service.CreateExportJob(inputElement.ExportJobTypeName, inputElement.ExportColumns, inputElement.ExportFilters, None, None, inputElement.Frequency)  

I get an error,

'list' object has no attribute 'id' 

Because a somewhat wrong XML request gets created

updatedSince

So I tried few other things for ExportFilter like

inputElement.ExportFilters.ExportFilter = [{'id': 'updatedSince', 'text': updatedSince}] 

and

inputElement.ExportFilters.ExportFilter = [('updatedSince', updatedSince)] 

and

inputElement.ExportFilters.ExportFilter = [{'updatedSince': updatedSince}] # says, Type not found: 'updatedSince' 

and

inputElement.ExportFilters.ExportFilter = [     {'key': 'updatedSince', 'value': {'key': 'eq', 'value': updatedSince}} ] # says, Type not found: 'value' 

but nothing is working.

Before setting ExportFilter, it's value is in the form of

ExportFilters: (ExportFilters){   ExportFilter[] =  } 

Please help.

After debugging and going through some suds code, I have found the fix.

The complete code snippet of the fix:

inputElement = client.factory.create('CreateExportJobRequest')  inputElement.ExportJobTypeName = "Products" inputElement.ExportColumns.ExportColumn = ["Id", "itemName"]  inputElement.Frequency = 'ONETIME'  if updatedSince:     efilter = client.factory.create("ExportFilter")     efilter._id = 'updatedSince'     efilter.Text = updatedSince     inputElement.ExportFilters.ExportFilter.append(efilter)  t = client.service.CreateExportJob(inputElement.ExportJobTypeName, inputElement.ExportColumns, inputElement.ExportFilters, None, None, inputElement.Frequency) 

Debugging: Because suds was raising TypeNotFound exception, I looked for all the places that raise TypeNotFound inside suds. I put debug points in my PyCharm.

I found that the start method from Typed class inside suds/mx/literal.py was raising the error I was getting.

def start(self, content):     #     # Start marshalling the 'content' by ensuring that both the     # 'content' _and_ the resolver are primed with the XSD type     # information.  The 'content' value is both translated and     # sorted based on the XSD type.  Only values that are objects     # have their attributes sorted.     #     log.debug('starting content:\n%s', content)     if content.type is None:         name = content.tag         if name.startswith('_'):             name = '@'+name[1:]         content.type = self.resolver.find(name, content.value)         if content.type is None:             raise TypeNotFound(content.tag)     else:         known = None         if isinstance(content.value, Object):             known = self.resolver.known(content.value)             if known is None:                 log.debug('object has no type information', content.value)                 known = content.type         frame = Frame(content.type, resolved=known)         self.resolver.push(frame)     frame = self.resolver.top()     content.real = frame.resolved     content.ancestry = frame.ancestry     self.translate(content)     self.sort(content)     if self.skip(content):         log.debug('skipping (optional) content:\n%s', content)         self.resolver.pop()         return False     else:         return True 

So from this logic, I came to the fix.

But, It would be really great if somebody suggests a standard procedure for this.
