# salesforce

A python connector for Salesforce

## connect
```
from salesforce import Connector

conn = Connector(username, password, security_token)
```

### connect to sandbox
```
from salesforce import Connector

conn = Connector(username, password, security_token, subdomain='test')
```

### optional parameters
```
max_reties = set a maximum number of retries
version = set a version other than the default, 44.0
client_id = id of the app to tag the call with
```

## select()

Pass in the name of the object, a list of the field names you want and the criteria with %s where your variables will go and a list of your values to identify which records to select.

Note that you will need to add single quotes around your %s placeholders if the field type requires it, like strings do.

A list of dictionaries will be returned.

```
from salesforce import Connector

conn = Connector(username, password, security_token)
fields = ['firstname', 'lastname]
criteria = 'WHERE id = %s'
values = ['003D000000QV9n2IAD']
results = conn.select('contact', fields, criteria, values)
```

### IN Criteria
This connector is set up to dynamically handle IN criteria.

For example the below will query Salesforce for: SELECT Id FROM Contact WHERE FirstName IN ('Sarah', 'James', 'Jamie')

Note that in the case of in criteria quotes will automatically be placed in the query for you if the variables in the list are type str.

```
from salesforce import Connector

conn = Connector(username, password, security_token)
fields = ['Id']
criteria = 'WHERE id IN %s'
values = [['Carey', 'Casey', 'Jamie']]
results = conn.select('contact', fields, criteria, values)
```

## create()
Pass in the object name and a dictionary with the data to use in the create.

```
from salesforce import Connector

conn = Connector(username, password, security_token)
data = {"FirstName": "Jamie",
        "LastName": "Doe",
        "Email": jdoe@gmail.com}
conn.create("Contact", data)
```

## update()
Pass in the id, object name and a dictionary with the data to use in the update.

```
from salesforce import Connector

conn = Connector(username, password, security_token)
record_id = "003advearera"
data = {"FirstName": "Carey"}
conn.create(record_id, "Contact", data)
```

## delete()
Pass in the id of the record to delete

```
from salesforce import Connector

conn = Connector(username, password, security_token)
conn.delete("003advearera", "Contact")
```

## Bulk Operations

These methods use the [Salesforce SObjects Collections endpoints](https://developer.salesforce.com/docs/atlas.en-us.api_rest.meta/api_rest/resources_composite_sobjects_collections.htm).

### General options
all_or_none: [Specifies whether you want one error to roll back the batch, or not.](https://developer.salesforce.com/docs/atlas.en-us.api_rest.meta/api_rest/requests_composite.htm) Remember batches are 200, so if you pass in over 200 records only the 200 in that batch will be rolled back. Batches before and after will proceed unless they also have errors.
batch_size: This defaults to 200, the maximum that Salesforce allows, but you can specify a smaller batch size if you want.

### bulk_create()
This method enables you to create records in batches of up to 200.

[Salesforce SObject Collections Create Endpoint Reference](https://developer.salesforce.com/docs/atlas.en-us.api_rest.meta/api_rest/resources_composite_sobjects_collections_create.htm).

If the records are all of the same type you can pass the object name directly in the bulk_change() call. If they are of different types you will need to use the add_attributes method to set the correct type information before using the bulk_change method.

For example this will create two contacts:

```
from salesforce import Connector

conn = Connector(username, password, security_token)
contacts = [{"FirstName": "Jamie",
             "LastName": "Doe",
             "Email": jdoe@gmail.com,
             "AccountId": "001qervaaer"},
            {"FirstName": "Carey",
             "LastName": "Doe",
             "Email": cdoe@gmail.com,
             "AccountId": "001qervaaer"}
            ]
conn.bulk_create(contacts, object_name = 'Contact')
```

This will create an Account and a contact:

```
from salesforce import Connector

conn = Connector(username, password, security_token)
contact = {"FirstName": "Jamie",
             "LastName": "Doe",
             "Email": jdoe@gmail.com,
             "AccountId": "001qervaaer"}
account = {"Name": "Fake Corp"}
acc_attr = conn.add_attributes(account, "Account")
cont_attr = conn.add_attributes(contact, "Contact")
conn.bulk_change([acc_attr, cont_attr])
```

### bulk_update()

This works the same way as the bulk create above except you need to include the record id in the payload.

[Salesforce SObjects Collections Update Endpoint Reference](https://developer.salesforce.com/docs/atlas.en-us.api_rest.meta/api_rest/resources_composite_sobjects_collections_update.htm)

### add_attributes()

This method enables you to easily add the object name to an object to make using the bulk create and update methods easier.

It also gives you the ability to add a referenceId, which makes finding the response for specific records easier, and any other kwargs you might need to add to the [attributes dictionary](https://developer.salesforce.com/docs/atlas.en-us.api_rest.meta/api_rest/responses_composite_sobject_tree.htm?search_text=referenceid) within your payload.

```
from salesforce import Connector

conn = Connector(username, password, security_token)
contact = {"FirstName": "Jamie",
             "LastName": "Doe",
             "Email": jdoe@gmail.com,
             "AccountId": "001qervaaer"}
attr_cont = conn.add_attributes(contact, "Contact", "jdoe@gmail.com")
```

### bulk_delete()

This method enables you to quickly delete multiple records. It is similar to the other bulk operations, but does not require a record type to be specified and accepts a list of Salesforce record ids instead of a list of dictionaries.

```
from salesforce import Connector

conn = Connector(username, password, security_token)
to_delete = ['0011qewavawer', '003averatea]
response = conn.delete(to_delete, False)
```


## Create Nested Records
Salesforce gives you the option to create parent and child records in one call. For example creating an Account with Contacts.

[Salesforce Composite Sobject Tree Create Endpoint Reference](https://developer.salesforce.com/docs/atlas.en-us.api_rest.meta/api_rest/dome_composite_sobject_tree_create.htm)

### nested_insert()
```
from salesforce import Connector

data = {
        "attributes" : {"type" : "Account", "referenceId" : "ref1"},
        "name" : "SampleAccount1",
        "phone" : "1234567890",
        "website" : "www.salesforce.com",
        "Contacts" : {
            "records" : [{
                "attributes" : {"type" : "Contact", "referenceId" : "ref2"},
                "lastname" : "Smith",
                "email" : "smith@salesforce.com"
                },{
                "attributes" : {"type" : "Contact", "referenceId" : "ref3"},
                "lastname" : "Evans",
                "email" : "evans@salesforce.com"
                }]
            }
        }
conn = Connector(username, password, security_token)
response = conn.nested_insert(data, 'Account')
```

### build_nested()
A helper to generate the data structure for the nested insert
```
from salesforce import Connector

account = {"name" : "SampleAccount1",
           "phone" : "1234567890",
           "website" : "www.salesforce.com"}
contacts = [{
            "lastname" : "Smith",
            "email" : "smith@salesforce.com"
            },{
            "lastname" : "Evans",
            "email" : "evans@salesforce.com"
            }]
attr_acc = conn.add_attributes(account, 'account', 'acc1')
attr_conts = [conn.add_attributes(c, 'contact', c['email']) for c in contacts]

conn = Connector(username, password, security_token)

nested = conn.build_nested('Account', attr_acc, {'Contacts': attr_conts}])
```

## call()
This method enables you to specify the url, method and data to send to Salesforce. You will probably want to use the create, update, delete, select, bulk_create, bulk_update, bulk_delete methods most of the time, but it gives you the option if there is functionality that is not covered here.
