A tested document ¶

This is a tested document. The following instructions are used for initialization:

>>> import lino
>>> lino.startup('lino_book.projects.min1.settings.doctests')
>>> from lino.api.doctest import *
>>> from django.db.models import Q

Database structure ¶

This plugin defines the following database models.

The main models are Person and Company and their common base Partner. The Partner model is not abstract, i.e. you can see a table where persons organizations are together.
A Role is when a given person has a given function in a given company.
A RoleType ("Function") where you can configure the available functions.
A CompanyType model can be used to classify companies.

Dependencies ¶

This plugin needs lino_xl.lib.countries and lino.modlib.system.

This plugin is being extended by Lino Welfare in lino_welfare.modlib.contacts or by Lino Voga in lino_voga.modlib.contacts.

Partners ¶

A Partner is any physical or moral person for which you want to keep contact data (address, phone numbers, ...).

A partner can act as the recipient of a sales invoice, as the sender of an incoming purchases invoice, ...

A partner has at least a name and usually also an "official" address.

Predefined subclasses of Partners are Person for physical persons and Company for companies, organisations and any kind of non-formal Partners.

class lino_xl.lib.contacts.Partner¶

The Django model used to represent a partner.

name¶

The full name of this partner. Used for alphabetic sorting.

Subclasses may hide this field and fill it automatically, e.g. saving a Person will automatically set her name field to "last_name, first_name".

prefix¶

An optional name prefix. For organisations this is inserted before the name, for persons this is inserted between first name and last name.

See lino.mixins.human.Human.get_last_name_prefix().

email¶: The primary email address.

phone¶

The primary phone number.

Note that Lino does not ignore formatting characters in phone numbers when searching. For example, if you enter "087/12.34.56" as a phone number, then a search for phone number containing "1234" will not find it.

gsm¶: The primary mobile phone number.

language¶: The language to use when communicating with this partner.

purchase_account¶

The general account to suggest as default value in purchase invoices from this partner.

This field exists only when lino_xl.lib.ledger is installed. It is defined as the invoice_account_field_name for TradeTypes.purchases.

Two fields exist only when lino_xl.lib.vat is installed:

vat_regime¶: The default VAT regime to use on invoices for this partner.

vat_id¶: The national VAT identification number of this partner.

Persons ¶

class lino_xl.lib.contacts.Persons¶: Shows all persons.

class lino_xl.lib.contacts.Person¶

A physical person and an individual human being. See also The Human mixin.

name¶

first_name¶

last_name¶

Organizations ¶

class lino_xl.lib.contacts.Company¶

class lino_xl.lib.contacts.Companies¶

An organisation. The verbose name is "Organization" while the internal name is "Company" because the latter easier to type and for historical reasons.

type¶: Pointer to the CompanyType.

name¶

street¶

gsm¶

phone¶: These fields (and some others) are defined in the base model Partner, they are what companies and persons have in common.

Quick search ¶

When doing a quick search in a list of partners, Lino searches only the name field and not for example the street.

>>> rt.show(contacts.Partners, quick_search="berg")
==================== ===== =========================== ================
 Name                 ID    See as                      e-mail address
-------------------- ----- --------------------------- ----------------
 Altenberg Hans       114   Organization, **Partner**
 Garage Mergelsberg   104   **Partner**, Person
==================== ===== =========================== ================

Without that restriction, a user who enters "berg" in the quick search field would also get e.g. the following partners (because their address contains the query string):

>>> rt.show(contacts.Partners, column_names="name street",
...     filter=Q(street__icontains="berg"))
===================== ===================
 Name                  Street
--------------------- -------------------
 Bastiaensen Laurent   Am Berg
 Collard Charlotte     Auf dem Spitzberg
 Ernst Berta           Bergkapellstraße
 Evers Eberhart        Bergstraße
 Kaivers Karl          Haasberg
 Lazarus Line          Heidberg
===================== ===================

This behaviour is implemented using the quick_search_fields attribute on the model.

>>> contacts.Partner.quick_search_fields
(<django.db.models.fields.CharField: prefix>, <django.db.models.fields.CharField: name>, <django.db.models.fields.CharField: phone>, <django.db.models.fields.CharField: gsm>)

Numeric quick search ¶

You can search for phone numbers

>>> rt.show(contacts.Partners, quick_search="123", column_names="name phone id")
====================== ============== =====
 Name                   Phone          ID
---------------------- -------------- -----
 Arens Andreas          +32 87123456   112
 Arens Annette          +32 87123457   113
 Dobbelstein Dorothée                  123
====================== ============== =====

Quickly finding a partner using its primary key ¶

A special type of quick search is when the search string starts with "#". In that case you get the partner with that primary key.

>>> rt.show(contacts.Partners, quick_search="#123", column_names="name phone id")
====================== ======= =====
 Name                   Phone   ID
---------------------- ------- -----
 Dobbelstein Dorothée           123
====================== ======= =====

This behaviour is the same for all subclasses of Partner, e.g. for persons and for organizations.

>>> rt.show(contacts.Persons, quick_search="berg")
=================== ============================= ================ ======= ===== ===== ==========
 Name                Address                       e-mail address   Phone   GSM   ID    Language
------------------- ----------------------------- ---------------- ------- ----- ----- ----------
 Mr Hans Altenberg   Aachener Straße, 4700 Eupen                                  114
=================== ============================= ================ ======= ===== ===== ==========

>>> rt.show(contacts.Companies, quick_search="berg")
==================== ============================= ================ ======= ===== ===== ==========
 Name                 Address                       e-mail address   Phone   GSM   ID    Language
-------------------- ----------------------------- ---------------- ------- ----- ----- ----------
 Garage Mergelsberg   Hauptstraße 13, 4730 Raeren                                  104
==================== ============================= ================ ======= ===== ===== ==========

Exporting contacts as vcard files ¶

class lino_xl.lib.contacts.ExportVCardFile¶

Download all records as a .vcf file which you can import to another contacts application.

This action exists on every list of partners when your application has use_vcard_export set to True.

Reference ¶

class lino_xl.lib.contacts.Plugin¶

region_label¶: The verbose_name of the region field.

with_roles_history¶: Whether to define two additional fields Role.start_date and Role.end_date.

use_vcard_export¶

Whether Lino should provide a button for exporting contact data as a vcf file.

If you set this to True, then you must install vobject into your Python environment:

pip install vobject

User roles ¶

class lino_xl.lib.contacts.SimpleContactsUser¶: A user who has access to basic contacts functionality.

class lino_xl.lib.contacts.ContactsUser¶: A user who has access to full contacts functionality.

class lino_xl.lib.contacts.ContactsStaff¶: A user who can configure contacts functionality.

Filtering partners ¶

class lino_xl.lib.contacts.PartnerEvents¶: A choicelist of observable partner events.

Other models ¶

class lino_xl.lib.contacts.CompanyTypes¶

class lino_xl.lib.contacts.CompanyType¶: A type of organization. Used by Company.type field.

class lino_xl.lib.contacts.RoleType¶

A function (RoleType) is what a given Person can be in a given Company.

TODO: rename "RoleType" to "Function" or "ContactType".

name¶: A translatable designation. Used e.g. in document templates for contracts.

class lino_xl.lib.contacts.Role¶

A role is when a given person exercises a given function (ContactType) in a given organization.

company¶: The organization where this person has this role.

type¶: The function of this person in this organization.

person¶: The person having this role in this organization.

start_date¶

When this person started to exercise this function in this organization.

This is a dummy field when Plugin.with_roles_history is False.

end_date¶

When this person stopped to exercise this function in this organization.

This is a dummy field when Plugin.with_roles_history is False.

class lino_xl.lib.contacts.ContactRelated¶

Model mixin for things that relate to either a private person or a company, the latter potentially represented by a contact person having a given role in that company. Typical usages are invoices or contracts.

Adds 3 database fields and two virtual fields.

company¶: Pointer to Company.

contact_person¶: Pointer to Person.

contact_role¶: The optional Role of the contact_person within company.

partner¶: (Virtual field) The "legal partner", i.e. usually the company, except when that field is empty, in which case partner contains the contact_person. If both fields are empty, then partner contains None.

recipient¶: (Virtual field) The Addressable object to use when printing a postal address for this. This is typically either the company or contact_person (if one of these fields is non-empty). It may also be a lino_xl.lib.contacts.models.Role object.

Difference between partner and recipient: an invoice can be issued and addressed to a given person in a company (i.e. a Role object), but accountants want to know the juristic person, which is either the company or a private person (if no company specified), but not a combination of both.

class lino_xl.lib.contacts.PartnerDocument¶: Deprecated. Adds two fields 'partner' and 'person' to this model, making it something that refers to a "partner". person means a "contact person" for the partner.

Print templates ¶

contacts/Person/TermsConditions.odt¶: Prints a "Terms & Conditions" document to be used by organisations who need a signed permission from their clients for storing their contact data. The default content may be localized.

======= ==================== ==================== ============================= =============================

class lino_xl.lib.contacts.CivilStates¶

The global list of civil states that a person can have. The field pointing to this list is usually named civil_state.

Usage examples are lino_welfare.modlib.pcsw.models.Client> and lino_tera.lib.tera.Client> and lino_avanti.lib.avanti.Client> .

The four official civil states according to Belgian law are:

single¶: célibataire : vous n’avez pas de partenaire auquel vous êtes officiellement lié

married¶: marié(e) : vous êtes légalement marié

widowed¶: veuf (veuve) / Verwitwet : vous êtes légalement marié mais votre partenaire est décédé

divorced¶: divorcé(e) (Geschieden) : votre mariage a été juridiquement dissolu

Some institutions define additional civil states for people who are officially still married but at different degrees of separation:

de_facto_separated¶

De facto separated (Séparé de fait, faktisch getrennt)

Des conjoints sont séparés de fait lorsqu'ils ne respectent plus le devoir de cohabitation. Leur mariage n'est cependant pas dissous.

La notion de séparation de fait n'est pas définie par la loi. Toutefois, le droit en tient compte dans différents domaines, par exemple en matière fiscale ou en matière de sécurité sociale (assurance maladie invalidité, allocations familiales, chômage, pension, accidents du travail, maladies professionnelles).

separated¶

Legally separated, aka "Separated as to property" (Séparé de corps et de biens, Getrennt von Tisch und Bett)

La séparation de corps et de biens est une procédure judiciaire qui, sans dissoudre le mariage, réduit les droits et devoirs réciproques des conjoints. Le devoir de cohabitation est supprimé. Les biens sont séparés. Les impôts sont perçus de la même manière que dans le cas d'un divorce. Cette procédure est devenue très rare.

Another unofficial civil state (but relevant in certain situations) is:

cohabitating¶

Cohabitating (cohabitant, zusammenlebend)

Vous habitez avec votre partenaire et c’est reconnu légalement.
