    copied!<p>I look an example of paginating from <a href="http://rapidprototype.ch/bg2docs/tg2pagination.html" rel="nofollow noreferrer">http://rapidprototype.ch/bg2docs/tg2pagination.html</a> for my Turbogears 2 project and it works great but, I have a problem regarding my query parameters when I change the page I'm looking.</p> <p>This is what I have in my controller when listing.</p> <pre><code>def list(self, page=1, **kw): q = "" if kw.has_key('q'): log.debug("searching %s" % kw) q = kw['q'] if kw.has_key('all'): q = "" products = DBSession.query(model.Product).filter( or_(model.Product.name.like('%%%s%%' % q), model.Product.description.like('%%%s%%' % q), model.Product.model.like('%%%s%%' % q), model.Product.code.like('%%%s%%' % q))).all() def get_link(product): return Markup("""&lt;a href="form?id=%s"&gt;%s&lt;/a&gt;""" % (product.id, product.id)) product_fields = [ (Markup("""&lt;a href="?s=id"&gt;Id&lt;/a&gt;"""), get_link), (u'Name', 'name'), (u'Model', 'model'), (u'Code', 'code'), (u'Description', 'description')] product_grid = MyDataGrid(fields = product_fields) currentPage = paginate.Page(products, page, items_per_page=50) return dict(currentPage=currentPage, title=u'Products List', item=u'product', items=u'products', data=currentPage.items, grid=product_grid, page=u'Search %s results' % q, q=q, hits=len(products)) </code></pre> <p>This is the html template fragment</p> <pre><code>&lt;h1&gt;List of ${items}&lt;/h1&gt; &lt;form action="list" method="get"&gt; &lt;input name="q" type="text" value="${value_of('q', default='')}"/&gt; &lt;input type="submit" value="Search"/&gt; &lt;input type="submit" name="all" value="All"/&gt; &lt;/form&gt; ${hits} ${items} found &lt;p class="pagelist"&gt;${currentPage.pager(format='$link_first ~3~ $link_last')}&lt;/p&gt; &lt;div&gt; ${grid(data)} &lt;/div&gt; &lt;p&gt;&lt;a href="${tg.url('form')}"&gt;Add a ${item}&lt;/a&gt;&lt;/p&gt; </code></pre> <p>The searches works fine resulting in links like this '<em>/list?q=cable</em>' but when I click some of the paginating pages "1,2...8,9" turns to '<em>/list?page=2</em>'</p> <p>How do I add my previous query parameter or any other parameters to the link?</p>
