Create a table in Prawn by its html representation

由 ﹥＞﹥吖頭↗ 提交于 2020-01-07 09:34:51
问题 Earlier Prawn gem allowed to create a table by its html representation (having an html table string as an input argument like <table class="abc"> .... </table> ). Now I didn't find this facility in the manual. So is it possible now? If not, is there any other option then? 回答1: TL;DR: if your use-case is 1) generating both HTML and PDF data (like online invoices etc.), and 2) making sure both look the same, then Prawn is not really the best solution (which is the same suggestion in the Prawn

Remove RVM, Ruby and gems completely?

由 旧街凉风 提交于 2020-01-06 03:38:05
问题 I had to downgrade Rails and now the gems, the versions, and everything, are completely messed up and I feel like jumping from my window. I just want to destroy everything related with RVM, Ruby and gems to make sure I make a 100% clean reinstallation. How can I do that? 回答1: Linux and installed as regular user ? Than all you need to do is: rm -Rf ./.rvm rm -Rf ./.gem rm -f ./.gemrc You can also check ~/.bashrc and ~/.bash_profile files for lines like this: PATH=$PATH:$HOME/.rvm/bin # Add RVM
