-Views & Templates
-=================
-
-
-Look at ``lax/skel/ginco/web/views/basetemplates.py`` and you will
-find the base templates used to generate HTML for your application.
-
-A page is composed as indicated on the schema below:
-
-.. image:: images/lax-book.06-main-template-layout.en.png
-
-In this section we will go through a couple of the primary templates
-you must be interested in, that is to say, the HTMLPageHeader,
-the HTMLPageFooter and the TheMainTemplate.
-
-
-HTMLPageHeader
---------------
-
-Let's use a different logo than the default one provided with LAX
-and customize our header.
-
-Change logo
-~~~~~~~~~~~
-
-The easiest way to use a different logo is to replace the existing
-``logo.png`` in ``myapp/data`` by your prefered icon and refresh.
-By default all application will look for a ``logo.png`` to be
-rendered in the logo section.

-ADD how to use external_resources variables used in ginco/web/webconfig.py
-
-Customize header
-~~~~~~~~~~~~~~~~
-
-Let's now move the search box in the header and remove the login form
-from the header. We'll show how to move it to the left column of the application.
-
-Let's sat we do not want anymore the login menu to be in the header, but we
-prefer it to be in the left column just below the logo. As the left column is
-rendered by ``TheMainTemplate``, we will show how to do it in TheMainTemplate_.
-
-First, to remove the login menu, we just need to comment out the display of the
-login component such as follows: ::
-
- class MyHTMLPageHeader(HTMLPageHeader):
-
- def main_header(self, view):
- """build the top menu with authentification info and the rql box"""
- self.w(u'<table id="header"><tr>\n')
- self.w(u'<td id="firstcolumn">')
- self.vreg.select_component('logo', self.req, self.rset).dispatch(w=self.w)
- self.w(u'</td>\n')
- # appliname and breadcrumbs
- self.w(u'<td id="headtext">')
- comp = self.vreg.select_component('appliname', self.req, self.rset)
- if comp and comp.propval('visible'):
- comp.dispatch(w=self.w)
- comp = self.vreg.select_component('breadcrumbs', self.req, self.rset, view=view)
- if comp and comp.propval('visible'):
- comp.dispatch(w=self.w, view=view)
- self.w(u'</td>')
- # logged user and help
- #self.w(u'<td>\n')
- #comp = self.vreg.select_component('loggeduserlink', self.req, self.rset)
- #comp.dispatch(w=self.w)
- #self.w(u'</td><td>')
-
- self.w(u'<td>')
- helpcomp = self.vreg.select_component('help', self.req, self.rset)
- if helpcomp: # may not be available if Card is not defined in the schema
- helpcomp.dispatch(w=self.w)
- self.w(u'</td>')
- # lastcolumn
- self.w(u'<td id="lastcolumn">')
- self.w(u'</td>\n')
- self.w(u'</tr></table>\n')
- self.template('logform', rset=self.rset, id='popupLoginBox', klass='hidden',
- title=False, message=False)
-
-
-
-.. image:: images/lax-book.06-header-no-login.en.png
-
-Let's now move the search box in the top-right header area. To do so, we will
-first create a method to get the search box display and insert it in the header
-table.
-
-::
-
- from ginco.web.views.basetemplates import HTMLPageHeader
- class MyHTMLPageHeader(HTMLPageHeader):
- def main_header(self, view):
- """build the top menu with authentification info and the rql box"""
- self.w(u'<table id="header"><tr>\n')
- self.w(u'<td id="firstcolumn">')
- self.vreg.select_component('logo', self.req, self.rset).dispatch(w=self.w)
- self.w(u'</td>\n')
- # appliname and breadcrumbs
- self.w(u'<td id="headtext">')
- comp = self.vreg.select_component('appliname', self.req, self.rset)
- if comp and comp.propval('visible'):
- comp.dispatch(w=self.w)
- comp = self.vreg.select_component('breadcrumbs', self.req, self.rset, view=view)
- if comp and comp.propval('visible'):
- comp.dispatch(w=self.w, view=view)
- self.w(u'</td>')
-
- # logged user and help
- #self.w(u'<td>\n')
- #comp = self.vreg.select_component('loggeduserlink', self.req, self.rset)
- #comp.dispatch(w=self.w)
- #self.w(u'</td><td>')
-
- # search box
- self.w(u'<td>')
- self.get_searchbox(view, 'left')
- self.w(u'</td>')
-
- self.w(u'<td>')
- helpcomp = self.vreg.select_component('help', self.req, self.rset)
- if helpcomp: # may not be available if Card is not defined in the schema
- helpcomp.dispatch(w=self.w)
- self.w(u'</td>')
- # lastcolumn
- self.w(u'<td id="lastcolumn">')
- self.w(u'</td>\n')
- self.w(u'</tr></table>\n')
- self.template('logform', rset=self.rset, id='popupLoginBox', klass='hidden',
- title=False, message=False)
-
- def get_searchbox(self, view, context):
- boxes = list(self.vreg.possible_vobjects('boxes', self.req, self.rset,
- view=view, context=context))
- if boxes:
- for box in boxes:
- if box.id == 'search_box':
- box.dispatch(w=self.w, view=view)
-
-
-
-
-HTMLPageFooter
---------------
-
-If you want to change the footer for example, look
-for HTMLPageFooter and override it in your views file as in:
-::
-
- form ginco.web.views.basetemplates import HTMLPageFooter
- class MyHTMLPageFooter(HTMLPageFooter):
- def call(self, **kwargs):
- self.w(u'<div class="footer">')
- self.w(u'This website has been created with <a href="http://lax.logilab.org">LAX</a>.')
- self.w(u'</div>')
-
-Updating a view does not require any restart of the server. By reloading
-the page you can see your new page footer.
-
-
-TheMainTemplate
----------------
-.. _TheMainTemplate:
-
-The MainTemplate is a bit complex as it tries to accomodate many
-different cases. We are now about to go through it and cutomize entirely
-our application.
-
-TheMainTemplate is responsible for the general layout of the entire application.
-It defines the template of ``id = main`` that is used by the application. Is
-also defined in ``ginco/web/views/basetemplates.py`` another template that can
-be used based on TheMainTemplate called SimpleMainTemplate which does not have
-a top section.
-
-.. image:: images/lax-book.06-simple-main-template.en.png
-
-CSS changes
------------
-
-We cannot modify the order in which the application is reading the CSS. In
-the case we want to create new CSS style, the best is to define it a in a new
-CSS located under ``myapp/data/``.
-
-If you want to modify an existing CSS styling property, you will have to use
-``!important`` declaration to override the existing property. The application
-apply a higher priority on the default CSS and you can not change that.
-Customized CSS will not be read first.
