Django form wizard save and go to previous step
问题 I have a working django formwizard which when I hit the previous button doesn't validate the current input. I've tried variations on <input name="wizard_goto_step" class="btn btn-primary btn-large" type="submit" value="prev"/> and <button class="btn btn-info btn-large" name="wizard_goto_step" type="submit" value="{{ wizard.steps.prev }}"> {% trans "prev step" %} </button> but neither of these seems to do what I want to do. 回答1: If you want it to validate and save the data on the current form
