How to set 'params'

When working with the client, user can often face the task to set attributes which are not found in object parameters. For this purpose params were introduced to every object. It is optional parameter in form of a dictionary where key is the name of the parameter found in WSDL (see How to query the model or model and application methods). Because it is set as the end of the routine, it can also override any parameters set previously.

Step by step

First, print the object of your interest on the command line using a script like this:

from suds.client import Client

client = Client('http://localhost:8081/wsdl')
new = client.service.get_active_model()+'wsdl'
model = Client(new)

print(model.service.get_nodal_support(1))

You will get full description of Nodal Support no.1. From this you can figure out the structure of the object and create whole new object with parameters and nested objects. For example, if you want to descibe support condition in X direction via diagram, focus on these parameters:

diagram_along_x_end = "DIAGRAM_ENDING_TYPE_CONTINUOUS"
diagram_along_x_is_sorted = True
diagram_along_x_start = "DIAGRAM_ENDING_TYPE_CONTINUOUS"
diagram_along_x_symmetric = True
diagram_along_x_table =
    (array_of_nodal_support_diagram_along_x_table){
        nodal_support_diagram_along_x_table[] =
            (nodal_support_diagram_along_x_table_row){
                no = 1
                description = None
                row =
                    (nodal_support_diagram_along_x_table){
                       displacement = -0.0001
                       force = -200000000.0
                       spring = 3900000000000.0
                       note = None
                   }
              },
             (nodal_support_diagram_along_x_table_row){
                no = 2
                description = None
                row =
                    (nodal_support_diagram_along_x_table){
                        displacement = -5e-05
                        force = -5000000.0
                        spring = 100000000000.0
                        note = None
                   }
             },
       }

You can then write:

NodalSupport(..., params = {'diagram_along_x_end':"DIAGRAM_ENDING_TYPE_CONTINUOUS"})

To define something like diagram_along_x_table nested structure must be properly populated:

diagram_along_x = model.clientModel.factory.create('ns0:response_spectrum.user_defined_response_spectrum')
for i,j in enumerate(nodal_support_diagrams):
    ns = model.clientModel.factory.create('ns0:nodal_support_diagram_along_x_table_row')
    ns.no = i+1
    ns.row.displacement= user_defined_spectrum[i][0]
    rsp.row.force= user_defined_spectrum[i][1]
    ns.row.force= user_defined_spectrum[i][2]

    diagram_along_x.nodal_support_diagram_along_x_table.append(ns)

NodalSupport(..., params = {'diagram_along_x_end':"DIAGRAM_ENDING_TYPE_CONTINUOUS", 'diagram_along_x_table' : diagram_along_x})

This is the process we use to develop this library, so if you're looking for something similar, many instances can be found throughout the project.
