TypeError: Object of type datetime is not JSON serializable

 

This error "TypeError: Object of type datetime is not JSON serializable" happens when we try to convert data with date time into json dictionary , so to fix this error we have to convert the data to string first then put it in the dictionary and then we can convert the dictionary to json format
...
for example if we want to create api with odoo to return the data for sale order , so we can put the sale order data as bellow 

order_data = {
            'id':order_id.id,
            'name':order_id.name,
            'customer':{'id':order_id.partner_id.id,'name':order_id.partner_id.name},
            'salesperson':{'id':order_id.user_id.id,'name':order_id.user_id.name},
            'date_order':str(order_id.date_order),
            'state':order_id.state,
            'products':order_products,
            'untaxed_amount':order_id.amount_untaxed,
            'total_tax': order_id.amount_tax,
            'total_amount':order_id.amount_total,
     }

return Response(json.dumps(order_data),headers=headers)

Display current company data

 In this blog we will explain how to display current company data in web page in odoo 14

First we can get the current company in the web page template by using
request.env.user.company_id


so we can show the current company logo by using 

<img t-if="request.env.user.company_id.logo" t-att-src="image_data_uri(request.env.user.company_id.logo)" style="max-height:45pt;max-width:90%" alt="Company Logo"/>

 

and we can show the current company name by using

<span t-esc="request.env.user.name"/>

and so on to display each field in the model res.company

cached report in odoo

    Let us say that we have report in odoo and we print it for the first time and then made changes in the data and after we print the report again it still show the first time report 

    For an example : we create an invoice with 1000 usd and register payment with 400 usd and print the invoice and the report show the payment , then we made another payment with 450 usd and when we print the report again it still show the first payment only and review the code and there is no error ???

    Now to fix this we have to go to settings/technical/actions/reports and search for the invoice report and open it to find a field with the name "Reload from Attachment " and set it to false as in the image bellow
