+Templates
+=========
+
+[WRITE ME]
+
+* talk about main templates, etc.
+
+
+
+Look at ``cubicweb/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
+--------------
+
+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 say 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 ``cubicweb/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.
