Connect Rails Application To Existing Database

允我心安 提交于 2021-02-07 04:32:30
问题 I have a client asking me to help them build a ruby application to interface with a database that was created for a different application that runs on php. The problem is that since the database was not scaffolded with rails, it does not follow any of the rails conventions. For example, there is a table called form If I run the command rails generate model form then rails will infer the table name is form s further more I don't want ruby to perform any migrations since the data is already

问题 Closed . This question is opinion-based. It is not currently accepting answers. Want to improve this question? Update the question so it can be answered with facts and citations by editing this post. Closed 6 years ago . Improve this question I see many saying "eval is evil/dangerous/insecure", because one can do things like: eval("os.system('rm -rf /')") while in other posts, pythoner are considered as " consenting adults ", you don't have to do type checking because of python is of style

Grouping Functions by Using Classes in Python

问题 I have been a Python Scientific Programmer for a few years now, and I find myself coming to a sort specific problem as my programs get larger and larger. I am self taught so I have never had any formal training and spent any time really on 'conventions' of coding in Python "properly". Anyways, to the point, I find myself always creating a utils.py file that I store all my defined functions in that my programs use. I then find myself grouping these functions into their respective purposes. One

Python proper use of __str__ and __repr__

核能气质少年 提交于 2021-02-04 17:14:22
问题 My current project requires extensive use of bit fields. I found a simple, functional recipe for bit a field class but it was lacking a few features I needed, so I decided to extend it. I've just got to implementing __str__ and __repr__ and I want to make sure I'm following convention. __str__ is supposed to be informal and concice, so I've made it return the bit field's decimal value (i.e. str(bit field 11) would be "3" . __repr__ is supposed to be a official representation of the object, so

C++ style: Stroustrup' s placement of pointer asterisks

眉间皱痕 提交于 2020-08-01 05:43:21
问题 Does anyone know why Stroustrup's style is the placement of pointers as follows? Specifically, what Stroustrup has provided for guidance about this matter? int* p; vs int *p; because declaring multiple variables would require the asterisk next to each variable name. Which would result in: int* p, *x; vs int *p, *x; In K&R C book, they explain that the asterisk/pointer is used as a mnemonic to aid in understanding. I find it odd that the pointer/asterisk is tied to the type, vs the variable as
