Template format undefined - suggested fix

[beerlington]

I had some issues rendering my *.html.erb templates. If I didn't specify the path as an option, it didn't know to to use the html format and would try to load .erb, without the "html. If I did specify the path, but the template loaded a partial called _.html.erb, it would have the same problem. The only solution I can find that works is to specify the template with:

@template.template_format = :html

Since all my templates are html, I have just put this in the make_pdf function within pdf_helper.rb. It could easily be setup as an option if you don't want HTML as the default template format when rendering a PDF.

I couldn't folow your advice but I did next (not very good solution)
def show
@Invoice = Invoice.find(params[:id])
get_extras

respond_to do |format|
  format.html # show.html.erb
  format.xml  { render :xml => @invoice }
  format.pdf  { redirect_to :action => :show_pdf, :template_format => :html}
end

end

def show_pdf
@Invoice = Invoice.find(params[:id])
get_extras
respond_to do |format|
format.html do
render :pdf => "invoice_"+params[:id],
:template => "invoices/show"
end
end
end

This is how I solved the issue.

def make_pdf(options = {})
  options[ :format ] ||= :pdf
  html_string = render_to_string_with_format( :template => options[:template], :layout => options[:layout], :format => options[:format] )
  w = WickedPdf.new(options[:wkhtmltopdf])
  w.pdf_from_string(html_string, options)
end
