Error: Hash Sum mismatch in GitLab

Recently, I have faced following error during instillation of Gitlab in Ubuntu.

odedra@odedra-Lenovo-Z50-70:~$ sudo apt-get install gitlab-ce
Reading package lists... Done

E: Unable to fetch some archives, maybe run apt-get update or try with --fix-missing?

Solution:

wget -c https://packages.gitlab.com/gitlab/gitlab-ce/ubuntu/pool/trusty/main/g/gitlab-ce/gitlab-ce_9.4.1-ce.0_amd64.deb

dpkg -i gitlab-ce_9.4.1-ce.0_amd64.deb

Above commands will download package manually and install in system. For more manual package list as per your System requirements.

ValueError Expected singleton in Odoo


Expected Singleton:

Class methods required single invoking object (Single Browsable Record) to invoke the method and suppose it will call by multiple invoking objects (Browsable Recordsets) then method is not able to identify for which object it should process, therefore it will raise an error Expected Singleton.

New API decorator is used to define method calling pattern whether methods allows only single object or multiple objects to invoke this method.


For Example:


if self.location_id:     #face ValueError Expected singleton because self contains multiple recordset.
 
    ########

Need to change with following:

for warehouse in self:

    if warehouse.location_id:

        ########


@api.one

This decorator loops automatically on Records of RecordSet for you. Self is redefined as current record

Note:

Caution: the returned value is put in a list. This is not always supported by the web client, e.g. on button action
methods. In that case, you should use @api.multi to decorate your method, and probably call self.ensure_one() in
the method definition.

@api.multi

Self will be the current RecordSet without iteration. It is the default behavior (multiple browsable objects). Methods which returns non premitive type data(list, dictionary, function) must be decorated with @api.multi 

@api.model

This decorator will convert old API calls to decorated function to new API signature. It allows to be polite when
migrating code. Self does not contain any record/recordset in methods which are decorated by this decorator.

So simply call like this

self.env['model_name'].method_name(arguments)

How to create server actions in Odoo 10?

Below is example of server actions in Odoo 8.

<?xml version="1.0" encoding="utf-8" ?>
<odoo>
    <data>
        <record id="action" model="ir.actions.server">
            <field name="name">My Action</field>
            <field name="model_id" ref="model_module_model"/>
            <field name="code">self.action(cr, uid, context=context)</field>
       </record>
    </data>
</odoo>

Following is example for Server actions in Odoo 10.

<?xml version="1.0" encoding="utf-8" ?>
<odoo>

    <data>
        <record id="action" model="ir.actions.server">
            <field name="name">My Action</field>
            <field name="model_id" ref="model_module_model"/>
            <field name="code">
           
            if context.get('active_model') == 'your.module.model' and context.get('active_ids'):
                    action = env['module.model'].browse(context['active_ids']).action()
          
            </field>
       </record>
    </data>
</odoo>


There is no need of self variable to declare server action in Odoo 10.

Error when override orm write method in Odoo 8 or 9

If you try override write method with following new API:

         @api.model
         def write(self, vals):
            ....
            return super(MyClass, self).write(vals)

You will see the following error:

        Traceback (most recent call last):
          File "/opt/odoo/odoo-server/openerp/http.py", line 530, in _handle_exception
            return super(JsonRequest, self)._handle_exception(exception)

            return checked_call(self.db, *args, **kwargs)
          File "/opt/odoo/odoo-server/openerp/service/model.py", line 113, in wrapper
            return f(dbname, *args, **kwargs)

            response = f(*args, **kw)
          File "/opt/odoo/odoo-server/addons/web/controllers/main.py", line 939, in call_button
            action = self._call_kw(model, method, args, {})
          File "/opt/odoo/odoo-server/addons/web/controllers/main.py", line 927, in _call_kw
            return getattr(request.registry.get(model), method)(request.cr, request.uid, *args, **kwargs)
          File "/opt/odoo/odoo-server/openerp/api.py", line 241, in wrapper
            return old_api(self, *args, **kwargs)
          File "/opt/odoo/odoo-server/openerp/api.py", line 239, in wrapper
            return new_api(self, *args, **kwargs)
        TypeError: write() got an unexpected keyword argument 'context'

Question: How to resolved mentioned error ?

Solution:

The method write should be decorated with decorator @api.multi. The mapping new API → old API defined by @api.model is inadequate (argument ids is missing).

Try with following code:

         @api.multi
         def write(self, vals):
            ....
            return super(MyClass, self).write(vals)

How to keep track of employee expenses?

Employee expenses are charges incurred on behalf of the company. The company then reimburses these expenses to the employee. The receipts encountered most frequently are:


  • car travel, reimbursed per unit of distance (mile or kilometer),
  • subsistence expenses, reimbursed based on the bill,
  • other purchases, such as stationery and books, destined for the company but carried out by the employee.

The expenses workflow

 

 * Record a new expense

Every employee of the company can register their expenses from Expenses application ‣ My Expenses. The workflow for personal expenses work that way:
  1. an employee record his expense, and submit it to the manager
  2. the manager approve or refuse the expense
  3. the accountant post journal entries
  4. the company reimburse the employee expense (the employee is like a vendor, with a payable account)
  5. if the expense is linked to an analytic account, the company can reinvoice the customer
For every expense, the employee should record at least:
  • a description: that should include the reference of the ticket / bill
  • a product: the expense type
  • a price (e.g. hotel) or a quantity (e.g. reimburse km if travel with his own car)
Depending of the policy of the company, he might have to attach a scan or a photo of the expense. To do that, just a write a message in the bottom of the expense with the scan of the bill/ticket in attachment.

If the expense is linked to a customer project, you should not forget to set an analytic account, related to the customer project or sale order (you might have to activate analytic accounts in the accounting settings to get this feature).
Once the expense is fully recorded, the employee has to click the button Submit to Manager.

In some companies, employees should submit their expenses grouped at the end of the month, or at the end of a business trip.

An employee can submit all his expenses in batch, using the Submit Expenses action from the list view of expenses, or the small icons in the list view.

* Validation by the manager

Managers should receive an email for every expense to be approved (the manager of an employee is defined on the employee form). They can use the menu To Approve to check all expenses that are waiting for validation.
The manager can:
  • discuss on an expense to ask for more information (e.g., if a scan of the bill is missing);
  • reject an expense;
  • approve an expense.

 

* Control by the accountant

Then, all expenses that have been validated by the manager should be posted by the accountant. When an expense is posted, the related journal entry is created and posted in your accounting.
If the accountant wants to create only one journal entry for a batch of expenses, he can post expenses in batch from the list view of all expenses.

 

* Reinvoice expenses to customers

If the expense was linked to an analytic account related to a sale order, the sale order has a new line related to the expense. This line is not invoiced to the customer yet and will be included in the next invoice that will be send to the customer (charge travel and accommodations on a customer project)
To invoice the customer, just click on the invoice button on his sale order. (or it will be done automatically at the end of the week/month if you invoice all your orders in batch)

 

* Reimburse the employee

If the expense was paid with the employee's own money, the company should reimburse the employee. In such a case, the employee will appear in the aged payable balance until the company reimburse him his expenses.
All you have to do is to create a payment to this employee for the amount due.

Login in Odoo with Google Acoount

This article will help us to login In Odoo with Google account.

If you have Google Apps then you probably want to allow your Odoo users to login with their Google account. The good news is Odoo supports OAuth authentication which means it plays nicely with Google Apps.

However setting this up can be quite tricky. In this guide I’m going to step you through the process so you can get it working first time.


Note that Google Apps is different to standalone GMail. You must follow each of the steps below in sequence otherwise your authentication process will fail.

There are six main steps:
  1. Enable OAuth authentication support in Odoo
  2. Enable the Google App Engine Admin Console in your Google Apps domain
  3. Create Google Apps OAuth2 access for Odoo
  4. Add Google OAuth2 credentials to Odoo
  5. Create a new Odoo user with Google Apps authentication
  6. Activating Google Apps authentication for new user
Important: Make sure Odoo is correctly configured to send email before starting this. Odoo will need to email an activation link when you enable OAUTH.

So, let’s get started.

Please follow steps for more details
