Model): _name = 'webob.infot' user_id = webob.info2one('webob.info', 'User') free_member = webob.infon(related='webob.info_member'). This field provides a virtual relationship towards multiple objects (inverse of many2one). Syntax: webob.info2many('webob.info', 'field_id(m2o)', 'Field name', . Many2one('webob.infoon', default=lambda self: self. . I confirm that: in v8 the default method for a many2one field must excellent tips.
When it creates harmful shortcuts. Some math teachers ban calculators, thinking students will use them to solve basic problems they should be able to solve on their own. Edtech presents us with a similar challenge: If we give every student an iPad from the age of 5, will they ever learn to use an actual library?
Will they develop healthy imaginations?

Exercise all five senses on a regular basis? This is something to watch out for. When it undermines deep learning. But if integrated inappropriately, it can backfire in a way that undermines all three skills. Be sure you are using technology to enhance the way students think, not just the way they memorise facts.
When it undermines basic learning. Take the calculator example again, for instance. We still need those basic skills. When it decreases interaction. At its best, technology is an incredible social tool, connecting people around the world.
But it can also reduce the chances of interaction and the learning experiences that come with it. Humans should learn from one another, not just from computers.
When it reduces the chance of failure. This is a big one. Mistakes create learning experiences. Without a struggle, we oftentimes end up with shallow learning and false confidence. When the appeal is purely aesthetic.
Relational Fields in OpenERP
When it contributes to information overload. Information overload will always limit learning, no matter how much information we are exposed to and how many tools we have to process it. Do not assume your students will be able to take longer tests just because they are encountering a greater volume of information. Believe it or not, the way you implement technology into your lessons is just as important as the decision to do so.
I remember playing Number Munchers in primary school. When students have already mastered the task. Sounds like a waste of time to me. When it hampers communication. Using properties or normal fields When you want to add a new feature, you will have to choose to implement it as a property or as normal field.
Use a normal field when you inherit from an object and want to extend this object. Use a property when the new feature is not related to the object but to an external concept.
Here are a few tips to help you choose between a normal field or a property: Normal fields extend the object, adding more features or data. A property is a concept that is attached to an object and have special features: This is a concept related to the account chart and not to the partner, so it is an account property that is visible on a partner form.
Rights have to be managed on this fields for accountants, these are not the same rights that are applied to partner objects. So you have specific rights just for this field of the partner form: This is a multi-company field: In a multi-company system, there is one account chart per company.
The account receivable of a partner depends on the company it placed the sale order.

The default account receivable is the same for all partners and is configured from the general property menu in administration. The account module depends on the partner base module. But you can install the partner base module without the accounting module.
If you add a field that points to an account in the partner object, both objects will depend on each other. Product Times The product expiry module implements all delays related to products: This module is very useful for food industries. This module inherits from the product.
We did not use properties because: We do not need a right management per field, the different delays are managed by the same people that manage all products.
When calling an ORM method, you will probably already have a context - for example the framework will provide you with one as a parameter of almost every method. If you do have a context, it is very important that you always pass it through to every single method you call.
