# Delete a task from a project in the database with blitzdb

# (Snippet, Other classes defined above)
def remove_task(self, title_or_id):

    # This is what i want to do:
    project = self.backend.filter(Project, {'title': 'some_project'})
    task = project.filter(Task, {'title': 'some_task'})
    self.backend.delete(task)

    # Or this (should return a task)
    task = self.backend.filter(Project, {'name': 'some_project',
                                               'tasks': [
                                                   {'name': 'task1'},
                                                   ]
                                              }
                              )
                              
    
    

# Here's the document i have

project = {
    'title': 'some_project',
    'desc': '',
    'tasks': [
        {'name': 'task1',
         'desc': '',
         'done': False,
        },
        {'name': 'task2',
         'desc': '',
         'done': False,
        }

    ]

}


# Here is the result i have like to retrieve and delete or just delete:

task = {
    'name': 'task2',
    'desc': '',
    'done': False,
}

# Am i just doing this all wrong? Could you point me in the right direction.
